Trims subtitle tiles before checking if it's full
Generalizes some stream parsing
Fixes an exception when a stream tag is set, but has no value
Looks for both subtitle and audio streams adjacent to the main file
Converters are now the result of combining multiple modules, and running them in the selected sequence. I hope to be able to completely remove converters by replacing them with templates that simply run some modules in a sequence, before running FFmpeg. Then I want to be able to parse a command into a template, so users have full control of what a template does.
Sorters each sort a list of streams after a single criteria. They can be chained in order to create complex chained sorters.
