A python script to merge two .srt subtitle files to a single .ass subtitle file, based on pysubs2.
Usage: ./mergesrt2ass.py SUBTITLE_FILE_1 SUBTITLE_FILE_2 OUTPUT_FILENAME.
The lines from SUBTITLE_FILE_1 will *probably* be displayed over the lines from
SUBTITLE_FILE_2. And the filename extension of OUTPUT_FILE should be ".ass".
