Python-jsonpath

**Fixes**

- Fixed `jsonpath.JSONPathMatch.path`. It is now a "normalized path" following section 2.7 of RFC 9525.
- Fixed normalized slice indexes. We were failing to normalize somme indexes given a negative step.

**Other changes**

- `jsonpath.match.NodeList` is now re-exported as `jsonpath.NodeList`.
- Added `jsonpath.NodeList.paths()`, which returns a list of normalized paths, one for each node in the list.
- Serialization of compiled JSONPath queries (instances of `jsonpath.JSONPath`) has changed. String literals inside filter selectors are now serialized using the canonical format, as described in section 2.7 of RFC 9525, and parentheses in filter selectors are kept to a minimum.

**Fixes**

- Fixed parsing of bare name selectors that start with a reserved word. See [issue 72](https://github.com/jg-rp/python-jsonpath/issues/72).

**Changes**

- We've dropped support for Python 3.7, which was end of life in June 2023.

**Fixes**

- Fixed the string representation regex literals in filter expressions. See [issue 70](https://github.com/jg-rp/python-jsonpath/issues/70).

**Fixes**

- Fixed handling of JSONPath literals in filter expressions. We now raise a `JSONPathSyntaxError` if a filter expression literal is not part of a comparison, membership or function expression. See [jsonpath-compliance-test-suite81](https://github.com/jsonpath-standard/jsonpath-compliance-test-suite/pull/81).
- Fixed parsing of number literals including an exponent. Upper case 'e's are now allowed.
- Fixed handling of trailing commas in bracketed selection lists. We now raise a `JSONPathSyntaxError` in such cases.

**Compliance**

- Skipped tests for invalid escape sequences. The JSONPath spec is more strict than Python's JSON decoder when it comes to parsing `\u` escape sequences in string literals. We are adopting a policy of least surprise. The assertion is that most people will expect the JSONPath parser to behave the same as Python's JSON parser. See [jsonpath-compliance-test-suite 87](https://github.com/jsonpath-standard/jsonpath-compliance-test-suite/pull/87).
- Skipped tests for invalid integer and float literals. Same as above. We are deliberately choosing to match Python's int and float parsing behavior. See [jsonpath-compliance-test-suite 89](https://github.com/jsonpath-standard/jsonpath-compliance-test-suite/pull/89).
- Skipped tests for incorrect casing `true`, `false` and `null` literals.

**Features**

- Allow JSONPath filter expression membership operators (`contains` and `in`) to operate on object/mapping data as well as arrays/sequences. See [55](https://github.com/jg-rp/python-jsonpath/issues/55).
- Added a `select()` method to the JSONPath [query iterator interface](https://jg-rp.github.io/python-jsonpath/query/), generating a projection of each JSONPath match by selecting a subset of its values.
- Added the `query()` method to the `JSONPath` class. Get a query iterator from an already compiled path.
- Added the `addne` and `addap` operations to [JSONPatch](https://jg-rp.github.io/python-jsonpath/api/#jsonpath.JSONPatch). `addne` (add if not exists) is like the standard `add` operation, but only adds object keys/values if the key does not exist. `addap` (add or append) is like the standard `add` operation, but assumes an index of `-` if the target index can not be resolved.

**Fixes**

- Fixed evaluation of JSONPath singular queries when they appear in a logical expression and without a comparison operator. Previously we were evaluating logical expressions with the value held by the single element node list, now we treat such filter queries as existence tests. See [57](https://github.com/jg-rp/python-jsonpath/issues/57).

**Fixes**

- Fixed logical operator precedence in JSONPath filter expressions. Previously, logical _or_ (`||`) and logical _and_ (`&&`) had equal precedence. Now `&&` binds more tightly than `||`, as per RFC 9535.
- Fixed JSONPath bracketed selector list evaluation order. Previously we were iterating nodes for every list item, now we exhaust all matches for the first item before moving on to the next item.

**Features**

- Added the "query API", a fluent, chainable interface for manipulating `JSONPathMatch` iterators ([docs](https://jg-rp.github.io/python-jsonpath/query/), [source](https://github.com/jg-rp/python-jsonpath/blob/7665105de1501a5b2172f63a88db6d08b2b1702d/jsonpath/fluent_api.py#L17)).
