- Fixed `Uuid` support, now represented as `Utf8` in Arrow and added testing logic. - Added `Duration` support, mapped to Arrow's `IntervalMonthDayNano`, with schema handling, decoding, and integration tests. - Updated `Cargo.toml` to include the `uuid` crate as a dev dependency for UUID checking. - Added integration tests with the new `duration_uuid.avro` test file.

- Changed `Uuid` from `Utf8` back to `FixedSizeBinary(16)` for proper Arrow UUID representation. - Removed `uuid` crate dependency. - Updated schema handling, decoding logic, and relevant tests for the new `Uuid` type. - Added utility functions and tests to parse UUID strings into binary format.

Thanks @jecsand838. I think it would be good to get at least one more review, because I'm not familiar with this crate.
- Introduced `canonical_extension_types` feature for standardized UUID handling. - Added `Uuid` crate dependency for parsing and validating UUIDs. - Updated `field_with_name` method to support canonical UUID representation. - Removed custom UUID parsing logic and replaced it with `Uuid` crate functionality. - Updated `Cargo.toml` accordingly.

Which issue does this PR close?
Part of Add Avro Support #4886
Related to Avro codec enhancements #6965
Rationale for this change
The
arrow-avrocrate currently lacks support for the Avrodurationtype, which is a standard and commonly used type in Avro schemas. This omission prevents users from reading Avro files containing duration types, limiting the crate's utility.This change introduces support for decoding Avro duration types by mapping them to the Arrow
Intervaltype. This is a logical and efficient representation. Implementing this feature brings thearrow-avrocrate closer to full Avro specification compliance and makes it more robust for real-world use cases.What changes are included in this PR?
