feat: Implement sd+jwt for issuance and verification flows with cloud agent (#228)

Signed-off-by: Javier Ribó <[email protected]>

BREAKING CHANGE:

Pollux instance now requires to have Apollo first constructor parameter (used internally)
Deprecated internal function processJWTCredential, processAnoncredsCredential and extractCredentialFormatFromMessage. Internally, in order to process any type of credential offer just call pollux.processCredentialOffer instead. In order to extract the credentialFormat from a DIDComm message if available, use message.credentialFormat (will return known CredentialType or unknown) In order to extract the payload of whatever DIDComm message, use message.payload which will decode it into the right object instance
JWT class now needs apollo and castor in constructor as they now instantiate from JWTCore (used internally)
Derivable Private key is not deriving using the derivationPath as a string not the DerivationPath class (used internally)
