EdDSA, sonarlint fixes, and cleanup (#16)

Browse Source 
* update commons-cli, dnsjava, remove gradle, set to java 17

* use baseAlgorithm enum instead of static ints

* sonarlint changes

* sonarlint/formatting for SignUtils

* sonarlint, formatting for RecordComparitor and JCEDnsSecSigner

* update a few defaults

* redo the SignZone logic around finding keys; more output for it.

* refactor getVerifier()

* sonarlint and formatting for the rest

* use SunEC for the algs 15, 16; support alg 16 finally

* address my self-review comments
