Support custom dict key types in JSON #602

Closed jcrist closed 11 months ago

jcrist commented 11 months ago

This adds support for encoding/decoding custom types when used as dict keys in the JSON encoder/decoder. Previously the JSON implementation failed to fallback to enc_hook/dec_hook for custom dict keys.

Fixes #568.
