Daemon mode

Is your feature request related to a problem? Please describe.
Not an animdl issue, we have sonarr but it doesn't do DDL, I often use DDL/XDCC for when sonarr fails to get a release I want for an airing anime. otherwise the season list becomes a mess of different dub/sub and sometimes quality due to naming schema and availability.

Also when sonarr chooses to do per episode instead of a season pack, leaving some episodes fail to actually download and process, making random missing episodes.

third reason: there's no DDL automated anime grabber. which would be nice for my local machine.

Describe the solution you'd like
new command:

• watch add "anime name" responds with a list of search results, manages a DB
  • --prior to also tell animdl to download previously aired
  • --first no prompts, just the first result.
  • --quality same format, keep things nice :3
  • --out set a specified output directory for the anime, since naming conventions vary and maybe you want some local and some put into a rclone mount
• watch remove self explanatory?
• watch start read below

my train of thought:
db should have [{name: "call of the night", outDir: "/home/NuzunaChan/anime/COTN/${format?}", quality: {idk}}, nextAir: DATE, meta: {}}]

• on an interval iterate through db to see if an episode has aired
• there's an aired episode!
• search sites for episode
  • not found, do nothing
• available!
  • does it match quality if configured?
• download to outDir
• after download, update nextAir

Other Points

• if it's the last episode or N/A, might cause issues, perhaps set the date to something insanely far away
• Completely dismiss upgrading video quality, shouldn't be needed right?
• DB per anime should contain a meta field to avoid having to grab the next episode name and other needed info every time.
• Naming, I don't think it matters too much, AnimeName - S00E00 or just AnimeName - E00, almost any media server or person can keep track of the literal episode number. output format would be best imo

Describe alternatives you've considered
the depth of 1-star github repos and some bad attempts at cronjob shell scripts, using xdcc-dl and subsplease packlist

Additional context
"Make a PR then"
no, I'm busy with work, watching one piece, and trying to put a media server on a switch
also upon searching I noticed there's no anime ddl daemon atm so.
