For some devices sending can be slow (as an example see SIM800, it can be up to 60s), command is being run properly but default timeout is returning an invalid error.
See https://www.elecrow.com/wiki/images/2/20/SIM800_Series_AT_Command_Manual_V1.09.pdf

When SMS list is big and baudrate is not fast enough, with default timeout we can suffer from timeout error while getting a sms because method is parsing the full list and this takes long.

…contained in SMS payload text

When parsing SMS, it can happen that we receive CRLF in the SMS payload (happened to me when receiving provider texts).
As an example, we can receive:

"""
Hello <CR><LF>
World!
"""

With previous implementation, second consume_to_stop_tag was stopping in <CR><LF> and rest of the code was failing for obvious reasons.
With this commit we consume the full payload as bytes.
