- Split most of the EspnowMeshBackend code into utility files and the new ConditionalPrinter, EspnowDatabase, EspnowConnectionManager, EspnowTransmitter and EspnowEncryptionBroker classes.

- Improve mutex handling.

- Move verifyEncryptionRequestHmac function from JsonTranslator to EspnowEncryptionBroker.

- Remove UtilityMethods.cpp.
