stm32mon: add option to replace the spinner

Browse Source 
Using only a Carriage Return as done to have a nice spinner is not
terribly compatible with logging the output of the tool to a file or
piping it to anything.
Add another option to have a simple progress-bar instead.

TEST=on Meowth, run flash_fp_mcu from the factory UI.
