Massive performance regression in deflate compression between rust 1.81 and 1.82 due to upstream rust compiler optimization issue

I was not informed of this so I wasn't aware of this change before now. Something did seem off with the compression speed when comparing to zlib when I started to do some more work on the library again recently but for whatever reason it didn't faze me to test older rust versions so I guess by chance I just happened to do comparisons again right after this regression

See rust issue rust-lang/rust#132636

As it looks like this a somewhat complex issue that isn't something that seems like it will be fixed any time soon I think it's probably best to see if we can find a way "work around" it.

Maybe better

Yeah that would be a cleaner approach if it works. It would bump the minimum rust version to 1.66 but I think that might be fine
