Merge pull request #14 from thesis/publish-to-npm

Add a GH Actions workflow publishing npm package with contracts

Contracts stored in the `thesis/solidity-contracts` repository are used
as a dependency in other projects. Currently they are pulled from the
GitHub and referenced to by commit hash.
In this PR we add a GH Actions workflow that will publish npm
packages containing `*.sol` contracts and version them using `-pre.X`
suffix.
