Since most of other jwt libraries in other languages have the R and S bytes reversed.
This has 2 optional features:
First you can enable inverted RS signature from ES256KSigner.invertedBytesR_S = true, this will reverse R bytes, reverse S bytes and concatenate both, this will enable the signatures to be verified by other libraries
Second you can enable ES256KVerifier.bouncyCastleFailSafe = true this will failsafe to reversing the bytes if the first verification fails. Providing verification for both case scenarios.
