[ci] move unix tests to Github Actions

- replace travis ci w/ github actions
- consolidates unix / windows tests
- adds testing against `Node v16`
- CI Runs every Sunday at Midnight for `Stable`, `Low`, & `High` tests

Stable tests run against Node `10`, `12`, `14`, & `16`
Low / High dependency tests run against Node `10` & `16`
All tests run on Windows & Linux

Failing `lowest` tests related to Typescript `v3.6.3` - to be fixed under separate PR
Node `10` support to be dropped in separate PR
