Increase AT timeout to 10s in AT_CellularSMS::send_sms 

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
