Quectel Delta Radio Firmware Upgrade support - libmts-io implementation

Small fixes and improvements.

1. Fixed casing for the "FUMO Error: timeout, radio is not responding" message.

   All error messages passed to the status callback shall start with "FUMO Error:"

2. Removed extra carriage return for the "abortFileUpload" command.

   Passing "+++\r" instead of the "+++" to the radio works for Quectel but cause
   issues for Telit.

   At the same time Quectel specificly requires to
   "Do not input any character within 1s after “+++” has been inputted."
   in their FILE manual. Possibly, "any character" includes carriage return.

3. Fixed a typo: "lenght" -> "length"
