Use new jsrsasign/jsjws

[PetrSnobelt]

Will be great if lib is compatible with breaking changes in jsrsasign/jsjws
Problem is described here
anvilresearch/connect-jwt#7
Until breaking changes are implemented, dependencies can be updated to
"jsrsasign": "4.9.2"

I don't feel enough experienced in this area to do it myself...

@PetrSnobelt – check out the webcrypto-api branch, which doesn't have this dependency at all. Struggling to find time to do the remaining testing and tweaks before merging, but several people have had very good luck with it so far.

Thank you Christian,
But I stay on webcrypto-api branch (with jsrsasign 4.9.2) due to caution on webcrypto-api branch
