Here are the CRC benchmarks per your request. I do see an execution failure in one case in CI, but my attempts to make sense of it have hit a dead end. I don't think it's related to this change, but can't be certain.

Yea, it's not your change, some fragility in a winforms test.

@brantburnett thank you for your contribution! Overall it looks good, but PTAL at my comments.

[adamsitnik]

Would you mind adding benchmarks for other methods? Like [GetCurrentHash()](https://learn.microsoft.com/en-us/dotnet/api/system.io.hashing.noncryptographichashalgorithm.getcurrenthash?view=dotnet-plat-ext-7.0#system-io-hashing-noncryptographichashalgorithm-getcurrenthash(system-span((system-byte)))) for example?

[brantburnett]

I added a test for GetCurrentHash. I didn't think any of the other methods warrant benchmarks, except possibly GetCurrentHashAsUInt32 or HashToUInt32. However, both of those are only available on the .NET 8 packages.

I did use separate classes for the GetCurrentHash tests because they don't need to run on different data lengths.

@adamsitnik is there anything that prevents this from merging?

[cincuranet]

I'm going to merge this as it is now and add the remaining benchmarks myself in separate PR.
