Move set_blosc! methods to H5ZBlosc.jl (#1167)

* Move `set_blosc!` methods to H5ZBlosc.jl

As far as I can tell, this usage of Requires was entirely unnecessary
since the package it was "extending" already depends on HDF5.jl

Co-authored-by: Gabriel Baraldi <[email protected]>

* Bump `docs` Manifest.toml

This is needed to pick up Documenter 1.4.0 which supports
fully-qualified `@ref` links.

* Fix downstream CI to dev filter packages

* Bump `H5Zblosc` version number and add compat bound

* Remove H5Zblosc `[compat]` bound

There's already an HDF5 compat bound in H5Zblosc - that one just needs
to be kept up-to-date.

* Move code to BloscExt rather H5Zblosc, reconcile other changes

* Refer to BloscExt.BloscFilter rather than H5Zblosc.BloscFilter

* Remove Julia 1.6 references from CI.yml
