Makes it possible to apply this filter without automatically converting to integers. #549

As noted in issue ( https://github.com/zarr-developers/numcodecs ), `vlen` had problems with read-only data Internally this occurred because we assigned the input array to `object[:]`, which expects mutability. Ideally we would...

I'm not sure why, but in https://github.com/zarr-developers/numcodecs/pull/501 c-blosc was updated to a commit that wasn't associated with a particular version. This PR updates c-blosc to v1.26.1, the latest release, which...

Time for some more version bumps to follow along with [SPEC-0](https://scientific-python.org/specs/spec-0000/#support-window)!

`pcodec` 0.3 was released recently, and it has breaking changes. For now I've pinned to `pcodec=0.3` and adapt numcodecs to work with the newer version.

Before https://github.com/zarr-developers/numcodecs/pull/619, it would be good to convert test warnings to errors, so we can make sure there aren't any warnings being raised that we're not expecting.
