KeyRef Values In Array Paths

Allow pointing to array elements via a reference field

Example path /array/id=123/data

First suggested in #139

This release incorporates that change and brings bsonpatch in line with zjsonpatch v0.5.0

• New Features

  • Added support for extended JSON Pointer syntax, allowing array elements to be referenced by key-value pairs (e.g. /array/id=123/data).
  • Enhanced escape sequence handling in JSON Pointer paths, including support for ~2 as a literal equals sign.

• Documentation

  • Updated README to describe the new extended JSON Pointer feature and provide usage examples.

• Tests

  • Added and expanded tests to verify parsing, evaluation, and escaping for the new array key reference syntax.
  • Introduced new test data for key reference scenarios.
