Description of the changes

Allow disabling cogs on a per guild basis (resolves #3945)

[mikeshardmind]

This should be ready to go now, though I won't be able to test the changes personally on this one until slightly later (can update this when that's happened unless others are interested in confirming this before I do)

[mikeshardmind]

Tested, updated, tested again and working as intended.

[mikeshardmind]

Updated for settable default state per discord discussion. Current state of PR is untested.

[mikeshardmind]

Rebased over the other changes to announcer made in #4089 , + uses the correct cog name

[mikeshardmind]

Reiterating something from before: anything after the initial commit has not been personally tested by me yet.

The initial commit (with message create cog disbale base [sic]) has been tested, but the changes made to accommodate a bot owner defaulting a cog to disabled has not yet (this is something I intend to handle this evening if time permits)

1. Streams cog should check if cog has been disabled in the guild it's checking stream alerts for.
2. (I am not entirely sure about this, but it's probably the right thing to do) Tempban expiration shouldn't happen for guilds that disabled the Mod cog.
3. I want @Drapersniper or @aikaterna to sign off on how this is used in Audio (I haven't checked that myself at all)

Everything else is in review comments.

1 & 2 are handled, as are the review comments.

As far as I could tell, everything in audio should be initiated by a command, the events won't be triggered without a corresponding command.

Other than the review of Audio parts, there's only one review comment left.

[Drapersniper]

just a quick FYI, there's a few events missing the check, Ill rewier it properly later today and note them down then.

[Jackenmen]

Looks good to me.
Just added 2 small code suggestion for strings that you can just merge
