Reads the the number of bytes specified by the variable 'bytes' out the given 'register'. This function requires a vector of integers as input ('data') and will return as output a new vector of the same size with the read data. This function returns a value ('updated') that becomes true when the data was received.

It is recommended to use the special read functions (readByte, readUInt8, readSInt8, readUInt16 and readSInt16).

If the read operation is not to an specific register, the input variable 'register' should be 0.
