Add multi-query support for "-q " and "-v" flag.

[MelaElezaj]

This PR merges the ability to input multiple queries through the '-q' flag and file-based input ('-v' flag) for added flexibility. The enhanced output now includes the respective query for each matched line in the 'matched_line_dict,' providing crucial context.

Thank-you!

Looks like it causes some issues with JSON output based on the failing unit tests (below). I'll take a look this week if I have time.

python3 -m unittest discover ./tests

Sorry for the delay and thanks for fixing the tests. Happy to be merging this now!

Thanks again
