idf_monitor: Ignore OS-level errors writing to Windows Console

Browse Source 
Windows Console write or flush may fail (throwing WindowsError, a subclass of OSError) if the data
written can't be displayed. This may be the case if the serial port is producing garbage bytes.

Ignore the error, in the hope that the serial port may "come good" and write non-garbage later.
