perf: remove asn1.js and use node-forge (#166)
* perf: remove asn1.js from rsa

* fix: tweaks

* fix: it works, but I do not know 100% why

* chore: remove asn1.js

* fix: ensure jwk params encoded as uint

* fix: util tests

* fix: zero pad base64urlToBuffer

* fix: more zero pad

* test: add round trip test

* test: base64url to Buffer with padding
