implementation of audio capabilities

The mux value is corrected if it is out of the supported range, but the uncorrected value was used to store the connection object. This caused subsequent dereferences of the corrected mux index to access incorrect data or dereference a null pointer.

To implement peek() as in https://github.com/vshymanskyy/TinyGSM/issues/396

Use data mode instead of text mode to be able to send any content such
as raw binary. This will allow us to use TinyGSM with ArduinoBearSSL and
ArduinoMqtt.

It should be noted that for an unclear reason GSM_NL must be set to '\n'
instead of '\r\n' to avoid "CME ERROR: operation not supported" in this
mode with the Monarch GMS01Q.

current connection technology

As specified in the ETSI standards (e.g. ETSI TS 127 001), CREG and
CEREG responses can contain optional parameters:

+CEREG:         <n>,<stat>[,<tac>,<ci>[,<AcT>]]

For example, the Monarch GMS01Q returns the following response:

+CEREG: 2,1,"3982","00DF3B03",7

This results in TinyGSM setting state as '7' instead of 1 preventing
any connection.

Fix this by picking the next integer after the first ',' which will
always works (with or without optional parameters)

There is an issue in the handling of +SQNSS answer: the
sock->sock_connected state will always be set to the state of the last
socket. This will prevent any communication.

Fix this issue by checking that muxNo is equal to mux before updating.

I refered TinyGsmClientSaraR4.h for this patch.
