Use PyQt5 to generate an executable small program: match the content in GGA format from the start keyword to the end keyword range, support multiple selection of files, and clear the copied files generated during the process.
The GGA file is as follows:
$GPZDA,063052.00,16,10,2023,,*61
$GPGGA,063052.00,4349.7377413,N,12509.8354912,E,4,40,0.6,222.928,M,0.00,M,01,2445*69
$GPZDA,063053.00,16,10,2023,,*60
$GPGGA,063053.00,4349.7377412,N,12509.8354914,E,4,40,0.6,222.926,M,0.00,M,01,2445*61
$GPZDA,063054.00,16,10,2023,,*67
