Nitro subscribers should be able to create DM groups of >10 people.

Hi, one feature that I would like to see in Nitro is the ability to create uncapped DM groups (or at least a higher cap).

I have run into the issue of having more people than a single DM group would allow, and am often in need of a disposable single-channel space that isn't a server. 

It shouldn't be difficult to implement, and it offers an additional perk to incentivize users into purchasing a subscription.
