Allow SPItransfer to be overridden by subclasses

Browse source 
This allows API clients to provide 'smarter' versions of Module that can do things like add thread safety so that multiple devices (and service threads) can share the same SPI bus. i.e. a subclass would lock some sort of mutex.

This is used in the Radiolib Fork for Meshtastic to share an SPI bus with SD Card and TFT Display but we want to move back to upstream and not maintain our own fork.
