Ci (#2)

* CI: Add scripts and all steps

#### Problem

This repo only contains the implementation of the program and CLI, with
no way of testing that it actually works.

#### Summary of changes

Get this repo in shape, based on the memo repo. Does the following:

* add CI for testing during PRs
* add publish step (only works with CLI currently)
* add dependabot
* add scripts
* update Cargo.toml to use crates version of spl-token
* add Cargo workspace
* add license
* add toolchain file / format file

* (temporary) Run main workflow for all PRs

* Revert branch change
