https://github.com/simdutf/SimdBase64 claims measurably faster Base64 decoding speeds than what's currently in .NET 9. We should consider switching over to that implementation or a variation thereof.

Support for VBMI2 in the runtime (https://github.com/dotnet/runtime/issues/88946) would make it profitable to add AVX-512 support to SimdBase64.
