Usage: $PROGRAM <option> path/to/pic16devices.txt > output.txt
Options are:
-o or --optimize
If a MCU features matches with an earlier listed MCU features,
then use the "using" keyword and with this method significantly
reduces the file size.
-u or --unoptimize
Unlocks the "using" keywords and displays the full original

-v <level> or --verbose <level>
It provides information on from the own operation.
Possible value of the level between 0 and 10. (default: 0)
