pcodec works at 4d32918

I'm going for zfpy but there is no sdist.

[d-v-b]

this looks like quite the saga

[mkitti]

Yes, quite the epic.

I think this will do for now, but I see some potential issues in the future.

The maintainace of zfpy upstream needs some attention.

[mkitti]

I think this is where I would want it to be for now.

We've added pcodec and zfpy to CI under a 32-bit Linux environment. We've even figured out how to build these from source in that 32-bit environment involving Rust and C++ toolchains.

I have some suspicion that zfpy may be linking against the system numpy and using the system cython in the current configuration. That said I'm not sure if zfpy is ready to be linked against numpy 2.x.
