Regex check for saved video files to get rid of unwanted symbols and replace spaces with underscores.
SampleDownloader now takes a json object instead of a dict.
Download videos will take start time, end time and clip size for each segment.
Last segment in each download will be combined with previous if less than total clip size (need to add a way to check if segment is greater than 60 seconds, then to generate a seperate clip)
