feat: License

[nickjuntilla]

What is the feature you would like to implement?
What is the license for your smart contracts? Is this OpenSource?

Why is this feature important?
I think it's important for us to have some clarity around the license so we can know if we can deploy for example on another blockchain. Can we expand on it? I think the ideal license for a decentralized OpenSource project would be MIT.

Will the protocol spec need to be updated??
Within protocol spec there should be a link to the License document.

Additional context
Right now the code is exposed and it appears to be open source, but there is no license, which can be confusing and also limiting.
