`KeyError: 'apply_tags'` when trying to edit movie tags

Describe the Bug

Attempting to edit a movies tags movie.edit(tags=["test"]) fails with the error: KeyError: 'apply_tags'. This appears to be an issue with snake_case vs camelCase case.

Steps to Reproduce

from arrapi import RadarrAPI

host_url = 'http://localhost:7878'
api_key = 'YOUR_KEY_GOES_HERE'
radarr = RadarrAPI(host_url, api_key)

# Just grab the first movie for this test
movie = radarr.all_movies()[0]

# Attempt to edit tags
movie.edit(tags=['test'])

NOTE: this assumes you have at least one movie in Radarr ;)
