NumpyJSONDecoder

Hello,

I see you have an extended class of JSONEncoder that allows saving into JSON types not supported by this class.
However, I can't seem to find the reverse class, allowing you to recover these types from json. Is it not implemented, or did I just not find it?

Thanks in advance,
Diogo Valada

Start by locating the extended JSONEncoder referenced in the issue and identify which additional types it supports. Check whether a reverse decoder already exists; if not, clarify the supported types and expected round-trip behavior before adding the decoder and tests.
