[improvement] Eslint GitHub action

[nolbuzanis]

Is your feature request related to a problem? Please describe.
There are some eslint errors that are present in the latest commit on master. Eslint is a good idea but it is not enforced at all.

Describe the solution you'd like
I've used the husky package to run a git pre-commit hook which runs npm run lint. This was all code that is committed would follow the eslint rules (or would knowingly ignore them).

Hi,
Personally I prefer to see this as a GitHub action, git hooks are really intrusive.
