The problem is its a 25% slow down for the pure python case

I think this still has potential if we use an lru since 99% of the data is the same

Type, class can be one key

Maybe similar to how we do it in aioesphomeapi. Use a cache wrapper that cython can convert from memory view to bytes and than py int to uint

Should work because view is really bytes on pure python anyways.

But is it faster...?

At least in pure python we probably reduce gc cycles by 99%

Maybe it's better to keep the specialized unpacks but use the views instead.
