Python __repr__

[arvidn]

cleanup repr and str in python binding to make all streamable types have a __repr__() based on the rust Debug trait. The BLS types also have a separate __str__().

The main objective with this is to make sure rust types have reasonable __repr__ implementations.

currently we get this:

>>> import chia_rs
>>> chia_rs.Coin(b"1" * 32, b"2" * 32, 1234)
<builtins.Coin object at 0x10051e070>

With this patch, we get this:

>>> import chia_rs
>>> chia_rs.Coin(b"1" * 32, b"2" * 32, 1234)
Coin { parent_coin_info: 3131313131313131313131313131313131313131313131313131313131313131, puzzle_hash: 3232323232323232323232323232323232323232323232323232323232323232, amount: 1234 }

The chia-bls types are special, because they need to be compatible with blspy so they have special handling and distinguish between Display (__str__) and Debug (__repr__).
