I was rummaging around the HDf5 documentation and found the function
H5Zregister (and associated other functions). Apparently they allow us to
bypass HDF5_PLUGIN_PATH and directly load dynamic filters. I have no idea
how I missed these. So this is a reminder to investigate and see if
this will provide an alternate way to load dynamic filters. It should allow
us to even use filters that are compiled into the client program.
In any case, see https://confluence.hdfgroup.org/display/HDF5/Filters

Allow in-line definition of filters

Priority: Low

re: issue #1329

HDF5 has the ability to programmatically define new filters,
as opposed to using HDF5_PLUGIN_PATH env variable.
This PR adds support for that feature.
Not clear how useful this is, though.
See docs/filters.md for details.
