Add `ECDSAKey` support to `JWKS`

This patch was authored and released by @JaapWijnen.

• Allows to create JWK's using ECDSAKeys
• Allows use of ECDSAKeys with JWTSigner.
• Prevents a crash when using the .es384 curve for ECDSAKeys

let key = ECDSAKey.generate(curve: .p384)
let jwks = JWKS(keys: [
   JWK.ecdsa(.es384, identifier: JWKIdentifier(string: "token-kid"), x: key.parameters!.x, y: key.parameters!.y, curve: .p384)
])

let key = ECDSAKey.generate(curve: .p384)
let signer = JWTSigner.es384(key: key)

Add RSAKey support for x509 certificate

This patch was authored and released by @tanner0101.

Adds support for initializing RSAKey from X.509 certificate pem files (#42).

Add support for Microsoft JWTs

This patch was authored and released by @tanner0101.

Adds new MicrosoftIdentityToken that supports Microsoft's JWT format (#36).

Support JWKs with no algorithm

This patch was authored and released by @tanner0101.

Adds support for JSON Web Keys that do not specify an algorithm (#34).

JWKs are now stored directly in JWTSigners via the use(jwk:) method. When a request to verify a JWT is received that matches a JWK, both the JWT and the JWK's algorithm header is checked. A signer is then created on the fly to handle the request.
