PC app: jtag: better handling of new line characters

Browse Source 
Previously the new line characters were expected to be
part of the feed request message. This is not so on
ESP32 based Arduino library implementation. The new
line characters arrive later on separately after a small
pause This code change fixes 'corrupted feed request'
warning messages on such Arduino platforms.
