- 👌 Improve parsing of nested amsmath

The previous logic was problematic for amsmath blocks nested in other blocs (such as blockquotes)

The new parsing code now principally follows the logic in `markdown_it/rules_block/fence.py`
(see also <https://spec.commonmark.org/0.30/#fenced-code-blocks>),
except that:

1. it allows for a closing tag on the same line as the opening tag, and
2. it does not allow for an opening tag without closing tag (i.e. no auto-closing)

- ✨ Add `allowed` option for inline/block attributes

The `allowed` option accepts a list of allowed attribute names.
If not ``None``, any attributes not in this list will be removed
and placed in the token's meta under the key `"insecure_attrs"`.

* 👌 Add option for footnotes references to always be matched

Usually footnote references are only matched when a footnote definition of the same label has already been found. If `always_match_refs=True`, any `[^...]` syntax will be treated as a footnote.

* ⬆️ UPGRADE: Drop python 3.7 and support 3.11 ([77](https://github.com/executablebooks/mdit-py-plugins/pull/77))

* ⬆️ UPGRADE: Allow markdown-it-py v3 ([85](https://github.com/executablebooks/mdit-py-plugins/pull/85))
* 👌 Make field_list compatible with latest upstream ([75](https://github.com/executablebooks/mdit-py-plugins/pull/75))
* 🔧 Convert `state.srcCharCode` -> `state.src` ([84](https://github.com/executablebooks/mdit-py-plugins/pull/84))
* 🔧 Remove unnecessary method arg by chrisjsewell in( [76](https://github.com/executablebooks/mdit-py-plugins/pull/76))
* 👌 Centralise code block test ([83](https://github.com/executablebooks/mdit-py-plugins/pull/83) and [#87](https://github.com/executablebooks/mdit-py-plugins/pull/87))
* This means that disabling the `code` block rule in markdown-it-py v3+ will now allow all syntax blocks to be indented by any amount of whitespace.

* 👌 Improve `dollarmath` plugin: Add `allow_blank_lines` option, thanks to [eric-wieser](https://github.com/eric-wieser) ([#46](https://github.com/executablebooks/mdit-py-plugins/pull/46))
