Implemented redundancy removal in tag function

The ComfyUI WD14 node uses the WD14 tagging models which often give redundant tags (e.g., they output both gloves and fingerless gloves or shirt and white shirt) so I threw this together to resolve some of that. Adding it into the async tag function helps clean up the output tremendously.

Removing exact duplicates

unique_tags = {}
    for tag, score in filtered:
        if tag not in unique_tags or score > unique_tags[tag]:
            unique_tags[tag] = score

    deduped = list(unique_tags.items())

Removing substrings

specific_tags = []
    for tag, score in deduped:
        is_subsumed = False
        for other, _ in deduped:
            if tag != other and tag in other and len(other) > len(tag):
                is_subsumed = True
                break
        if not is_subsumed:
            specific_tags.append((tag, score))

Additionally, the async tag definition was strangely hardcoding values that should be overridden by the user settings such as threshold, character threshold, exclude tags, etc. These now reference the defaults.
