Add orjson options in JSONStore

[gpetretto]

orjson, used for serialization in JSONStore, supports different options for serialization. This PR adds the possibility to pass down the option and default keywords for serialization, that allow to tune orjson's serialization behaviour.
In my case, I need to serialize the output of an atomate calculation and it contains FloatWithUnit, which is subclass of float and as such is not handled by orjson (ijl/orjson#114).

I have also fixed the close method of the GridFSStore, that was raising an exception.

I needed to bump orjson version, since the options were not available in the older version.

I have also noted that the fix in the GridFSStore should solve #733
