feat: Adding AES GCM support (#26)

* chore: use jest for tests

* tests: remove support for nodejs 12

* chore: add Jest types

* Adding GCM encryption support.

This adds GCM encryption. It is needed for newer firmware versions and replaces existing ECB for all pack encryptions BUT the scan command, which still runs on ECB for compatibility.

Tested on firmware 362001065279+U-WB05RT13V1.23

* feature: Add GCM encryption

* chore: cleanup
