Python-liquid

**Fixes**

- Fixed a bug where a class-based filter defining `filter_async` and setting `with_context` or `with_environment` to `True` would not be awaited. See [117](https://github.com/jg-rp/liquid/issues/117).

**Build**

- Fixed some package build issues since moving to [hatch](https://hatch.pypa.io/latest/). Both version 1.9.0 and 1.9.1 inadvertently included `.mypy_cache` folders, making the distribution files significantly larger.

**Fixes**

- Force the "wheel" build target to include `py.typed`.
- Restore `liquid.__version__`.

**Fixes**

- Changed `FileSystemLoader` so that loaded templates can be pickled. See [107](https://github.com/jg-rp/liquid/issues/107).
- Fixed the `liquid.Environment` template cache. Now, when given a `cache_size` of `0`, the cache is disabled. See [108](https://github.com/jg-rp/liquid/issues/108).

**Features**

- Added context-aware template loader bootstrapping methods. See [109](https://github.com/jg-rp/liquid/pull/109).
- Added support for async class-based filters. See [115](https://github.com/jg-rp/liquid/pull/115).
- Added `CachingFileSystemLoader`, a template loader that handles its own cache rather than relying on the `Environment` template cache, which can't handle context-aware loaders. See [116](https://github.com/jg-rp/liquid/pull/116).

**Fixes**

- Fixed comparison of strings in logical expressions. Previously we only supported comparing strings for equality with `==` and `!=`, now we support `<`, `>`, `<=` and `>=` too.
- Fixed handling of superfluous expressions in `{% else %}` tags. We now silently ignore anything between `else` and `%}`, matching the behavior of Shopify/Liquid.
- Fixed handling of extra `{% else %}` and `{% elsif %}` blocks after the first `{% else %}` block. We now silently ignore extraneous blocks, matching the behavior of Shopify/Liquid.

**Fixes**

- Removed unnecessary wrapping of inline conditional expressions in `BooleanExpression`.
- Fixed async evaluation of macro arguments. Previously they were always being evaluated synchronously.
- Allow `macro` names to be quoted or unquoted. Quoted and unquoted macro names are now equivalent when defining and/or calling a macro.

**Compatibility**

- Support bracketed variables without a leading identifier. See [Shopify/liquid 1680](https://github.com/Shopify/liquid/pull/1680).
- Allow whitespace control from `raw` tags. See [Shopify/liquid 1683](https://github.com/Shopify/liquid/pull/1683).

**Features**

- Added `{% extends %}` and `{% block %}` tags for template inheritance. These are extra tags that need to be registered with a `liquid.Environment` explicitly. ([docs](https://jg-rp.github.io/liquid/extra/tags#extends--block), [source](https://github.com/jg-rp/liquid/blob/main/liquid/extra/tags/extends.py))
- Added a new `sort_numeric` filter. `sort_numeric` returns a new list with items from the input sequence sorted by any integers and/or floats found in the string representation of each item. ([docs](https://jg-rp.github.io/liquid/extra/filters#sort_numeric), [source](https://github.com/jg-rp/liquid/blob/main/liquid/extra/filters/array.py#L35))

**Fixes**

- Fixed a bug with the `cycle` tag when using `liquid.future.Environment`. We were misinterpreting unquoted cycle group names as strings rather than variables to be resolved, and not Liquid stringifying some cycled items before output. We've also rolled back changes to `CycleNode.children()` from version 1.7.0.
- Fixed a regression bug that lead to some erroneous filtered expressions tokens to be silently ignored. Specifically any tokens that appear after a valid left value and the first filter or end of expression. We now raise a `LiquidSyntaxError` in such cases. See [103](https://github.com/jg-rp/liquid/issues/103).
- Fixed parenthesized conditional expression syntax error reporting. We now raise a `LiquidSyntaxError` when given unbalanced parentheses. See [101](https://github.com/jg-rp/liquid/issues/101).

**Compatibility**

- The `{% for %}` tag now accepts a string literal as its iterable. Unlike Shopify/liquid, whether a string literal or a variable resolving to a string, the default `Environment` will iterate over characters in the string. `liquid.future.Environment` is now consistent with Shopify/liquid, in that it iterates over an "array" where the first an only item is the string. See [102](https://github.com/jg-rp/liquid/issues/102).
- The `round` filter is now consistent with Shopify/liquid and Ruby 3 when given non-integer arguments. See [Shopify/liquid1590](https://github.com/Shopify/liquid/issues/1590).
