feat: added a method to check_index_paths(), this function accurately detects the correct extension for the selected indexer 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 fix: fixed a potential bug when it came to creating an index that didn't exist
