fix: a bug where the encode would attempt to use the source index file, generating a new one in it's place incorrectly (this was present in ffms2)
refactor: removed un-needed comments
feat: add support to select image generation library from the CLI
refactor: only import what we need from awsmfunc instead of the whole module

refactor: the default color is now set to a neon green color
feat: optimized code for indexing ffms2 and lsmash
feat: added the ability to accept direct paths to the index for both lsmash/ffms2
