jwkest.ecc.ECCException: Unknown curve

[panva]

Similar to #54 the suite fails to parse the JWKS keys when an unknown curve is present. In this case it's a known kty (EC) but an unknown crv.

Given that the known curve list is not finite but can be extended through IANA registry, the suite needs to ignore curves it's not ready for.

Error:
