Add tooling

[sparten11740]

• run checks in the CI (ci: run tests #10)
• add @exodus/eslint-config (chore: use @exodus/eslint-config #11)
• use semrel to release automatically on merge to master (ci: automatic releases #13)

@ChALkeR are you okay with me adding some tooling here?

[ChALkeR]

No. This is a public repo and package, it shouldn't even dev-depend on private ones.

it shouldn't even dev-depend on private ones

the two private dependencies it depends on will be open sourced soonish, so that shouldn't be an issue any more. Especially because this is a public repo there should be tooling that enforces standards.

[ChALkeR]

This can be unblocked once those are open-sourced.
Without that, this will introduce tooling that is broken instead.
