BIG_INT application command option type

[IllagerCaptain]

My idea for its implementation would be that it is sent to the bot as a string, but Discord on their end performs validation to ensure it is a valid integer. It would support min_value and max_value.

There are just some cases where numbers below 2⁵³ are just not enough.

In my specific case my bot has an input for a bitfield, but I had to switch it to use strings as there grew a need for huge bitfields, and in my opinion it's bad UX to not tell the user their input is invalid until after they send the command.

Regex strings would also work but I do not see that happening.
