Add sungwy/iceberg-testing as a pinned git submodule with language-neutral conformance fixtures (type strings, the Appendix B bucket hash, delete-file decode). The harness that walks them is deferred (see conformance/README.md); the PyIceberg fork has the worked example.

Pull request overview
This PR introduces a proof-of-concept setup for consuming language-neutral Apache Iceberg conformance fixtures by pinning sungwy/iceberg-testing as a git submodule, along with documentation describing the intended fixture “surfaces” and deferred C++ harness work.
Changes:
- Add
conformance/README.mddescribing the fixture surfaces (types parse/serialize, bucket KATs, delete-file decode) and how to consume them via the submodule. - Add
.gitmodulesto register theiceberg-testing/submodule pointing athttps://github.com/sungwy/iceberg-testing.git.

POC pinning the language-neutral conformance fixtures from sungwy/iceberg-testing as a git submodule (
iceberg-testing/).Surfaces: type-string parse + re-serialize, the Appendix B bucket-hash Known-Answer-Test (incl. byte-boundary decimals), and delete-file decode by field-id.
The harness that walks them is deferred in this POC (no toolchain available to build and verify it here) — see
conformance/README.md. The worked example is the PyIceberg fork: sungwy/iceberg-python#1
