sun.misc.Unsafe usage in Zero-Allocation-Hashing will be deprecated - what is Parquet's plan?

### Describe the bug, including details regarding any error messages, version, and platform.

The parquet-java repo depends on the [Zero-Allocation-Hashing](https://github.com/OpenHFT/Zero-Allocation-Hashing) library. That library uses `sun.misc.Unsafe`, which is being deprecated. As of the already-released JDK 24, uses of that library emit warnings (see [JEP 498](https://openjdk.org/jeps/498)). The library is slated to be deprecated after JDK 26, which probably means JDK 27 (or later). JDK 27 is scheduled to be released in September 2026.

So, parquet-java has two options:
1) Wait for Zero-Allocation-Hashing to migrate away from uses of `sun.misc.Unsafe`. There is [an issue](https://github.com/OpenHFT/Zero-Allocation-Hashing/issues/94) in that repo for this work. However, it's unclear to me how much attention the repo gets. The last release was in 2021, and the last commit was 5 months ago. So, parquet-java may or may not be able to rely on that repo to do the required fixes.
2) Use another library, which does not use sun.misc.Unsafe.
3) Write a new version, inside the parquet-java repo.

I want to bring this issue up so the contributors here are aware of the issue. What should the next steps be?
