Subject: [PATCH] chore: add RFC9535 compliance test suite (#81)

This change adds the RFC9535 compliance test suite to the project from
https://github.com/jsonpath-standard/jsonpath-compliance-test-suite.
Many of the test cases are failing so the included test in lib.rs is
suppressed for now and only used to print an informative summary.
