Automatically leave bot spam servers before we initialize them.

Is your feature request related to a problem? Please describe.
ClemBot is often added to spam servers with human/bot ratios of upwards of 1000:1.

These servers cause immense spam load on Clembots limited infrastructure.

We need to check this ratio before we init the server and leave it if the bot number is too high

Example spam server:

What kind of a ratio would be ideal? I'm thinking 0.2-0.25 given there's more than 25 or so users.

We may also want to take into account lower quantities of users & bots and ignore if they're low enough (i.e., user count is 1 and bot count is 3).
