Extend HDF5 compression options

[djps]

Is your feature request related to a problem? Please describe.
The hdf_compression_level: Optional[int] should also except a number of strings so that other compression algorithms supported by h5py can be used, such as lzf

Describe the solution you'd like
Ensure the proper arguments can be passed.

It might make sense to make the argument an enum to be able to type the options. Also this would prevent the int/string type mixing.

Tracked by #332 (Extend HDF5 compression options). Will close when that PR merges.
