Updated the function: readSubscription
Change: Updated bug where packets > 128 characters were scrapped
Bug fixed: Updated the references to the bytes to adapt for the variable number of "length" bytes that are included (MQTT docs specify a maximum of 4 "length" bytes.
Remaining possible issues: No error checking to ensure that the packet length parameter is within the limits of the MQTT spec (4 length bytes maximum)
