Ci (#2)

* Use crates.io crates, fix spell-check and build

* CI: Add scripts and repo setup

#### Problem

This repo only contains the implementation of the program / CLI / JS /
python bindings, with no way of testing that any of it works.

#### Summary of changes

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

* add CI for testing during PRs
* add dependabot
* add scripts
* add Cargo workspace
* add license
* add toolchain file / format file
* update maintainers to Anza
* add publish scripts for JS and CLI
* fix build issues

* (Temporary) always run CI

* Add more deps for CLI build

* Add purge step

* Revert "(Temporary) always run CI"

This reverts commit 3c640f6.
