### Improve Kit initialization Right now the initializer of the Kit class takes a wallet parameter but It is not used: [see](http://github.com/blaize-tech/celo-sdk-py/blob/32bb8f2a593b152ec0b3fe2f8fe75d3b9ebf2563/celo_sdk/kit.py#L21-L21) Since a Wallet object it's been initialized there I think It would be better to accept the private key and initialize the Wallet with said argument. I have the change in my local machine if you want I could open a PR with this minor change!
