Added the "2021", "4_toes", "anus", "black_body", "black_fur", "black_spots", "black_toenails", "brown_body", "brown_fur", "brown_spots", "chest_tuft", "claws, "dewclaw", "elbow_tufts", "feet", "fingernails", "fingers", "fur", "green_eyes", hair", "inner_ear_fluff", "mottled", "mottled_body", "mottled_fur", "multicolored_body", "multicolored_feet", "multicolored_fur", "multicolored_legs", "multicolored_tail", "nails", "paws", "pink_nipples", pink_nose", "pink_pawpads", "pink_pussy", "red_hair", "spots", "spread_toes", toe_claws", "toes", and "tuft" tags.

I added the tags mainly for the lack of "spread_toes" and "anus" tags and also the lack of body part related tags. Most of the others were to expand the number of tags. With the "dewclaw" tag, I wasn't 100% sure about but I added it anyway since the appendages on the inner part of the feet look like a dewclaw to me.
