Add support for Map / Sequence tensors inputs

[kylexqian]

• Input side: We need to convert user map / sequences to python type (no Numpy) -- web3 users don't need to worry about this because they don't use numpy types I'm assuming...
• Output side: I want to render the outputs properly, since they're JSON strings we should deserialize them so they print properly.

We have users using these types so I'm setting priority to P0

#65
Added output support for JSON tensors. Waiting on input support changes on the sequencer side, then we'll need to support those on the SDK too.

This is slightly tricky as we'll have to have some way of differentiating between NumberTensor, StringTensor, and JsonTensor user inputs now -- can't just rely on the python typing because JsonTensor are just dicts / arrays that need to be converted to strings.
