[Feature]: Email user when they've been banned

Checked Existing

• I have checked the repository for duplicate issues.

What feature do you want to see added?

When a user is banned, email them the relevant ban details. If a console is banned, send the email to all accounts linked to the console.

Why do you want to have this feature?

Currently user bans are not very transparent. Only Juxtaposition tells the user why they are banned, for how long, etc. This kind of functionality should be extended to the whole network.

Currently some work and proposals by @ashquarky and @shutterbug2000 to add this to Inkay, via hooking the error displaying and downloading the ban reason from our servers, has been done. While this is nice, it has 2 major issues:

• Increases the time it takes to show ban errors due to needing to make a full HTTP request for the data
• Only really works on Inkay. This does nothing for users who only use emulators and those who only use the 3DS

While I believe adding this to Inkay is still worth it, it should not be the ONLY way to see your ban information.

Any other details to share? (OPTIONAL)

Relies on #106

Another possible option is to take the Wiimmfi approach and publicly show the list of bans. https://wiimmfi.de/show-bans
It has the nice benefit of making a public statement that we do actually enforce this and discourages people who think they can't be caught.

I do believe this idea was brought up on Discord a while ago, but we never settled on if we should or not. I remember there being push back, due to similar reasons for not wanting ban appeals to be public (although I am in favor of making bans public).

Even if we do make them public though, we still ought to have direct communication with the user.
