In pursuit of removing skips in the integration test for apache/arrow#49910 . While the IPC reader has supported Decimal 32 and 64 since the beginning, the JSON parser hasn't.

The file reader for the integration tests also was never updated to support dictionary batches. To fully support the integration test we also need a writer for dictionaries which is a bit more involved and I'll do it in another PR.
