Minor Version Release 0.3.0

Major Changes include:
* Signature change in vss-client constructor. (in lightningdevkit#31 )
* Vss-client can now also return AuthError if AuthException is returned from server. (lightningdevkit#30)
* Adds VssHeaderProvider, can be used for auth and request signing.(lightningdevkit#31)
* Adds LnurlAuthToJwtProvider, provides LnUrl based JWT auth. (lightningdevkit#26)
* Adds KeyObfuscator, to provide client-side key obfuscation. (lightningdevkit#32)
* Package now has enforced MSRV of 1.63.0. (lightningdevkit#19)

This is a minor version bump because there are non-backward compatible changes in vss-client usage.
