Update CTS and fix

[jg-rp]

Update the compliance test suite and fix some issues.

• Fixed decoding of escape sequences in quoted name selectors and string literals. We now raise a JSONPathSyntaxError for invalid code points.
• Fixed parsing of number literals with an exponent. We now allow 'e' to be upper case.
• Fixed handling of trailing commas in bracketed segments. We now raise a JSONPathSyntaxError in such cases.
• Fixed handling of invalid number literals. We now raise a syntax error for invalid leading zeros and extra negative signs.

See:

• Add tests for invalid surrogate pairs jsonpath-standard/jsonpath-compliance-test-suite#87
• Add tests for invalid and uncommon filter literal values jsonpath-standard/jsonpath-compliance-test-suite#89
