[ENHANCEMENT]: web-crypto support

[markusahlstrand]

Is your feature request related to a problem? Please describe...

I would like to use xml-crypto in WinterCG environments like cloudflare workers.

Describe teh solution you'd like...

Replace the dependency on node crypto with web-crypto. It should be backwards compatible to node 16.

Describe the alternatives you've considered...

There seems to be no easy way to shim the node-crypto library. As web-crypto async it also requires the interfaces to update which makes the changes needed fairly large.

I am working on this, see my fork

It looks like it could be done without to many changes by using the callback and implementing a new hash-algorithm and signature-algorihm. Maybe this is good grunt work for Claude :)

Tried it out and did a PR: #513 . It is AI generated but I also reviewed it and checked it with code rabbit. It's a pretty big change so I'm not sure it really fits into the scope of this project? If not just let me know and I'll use the fork instead and try to keep it up to date.
