Add an option to request a game in a range of time limits, to get an opponent quicker.

I often wouldn’t mind playing any long time frames, from 10 mins to 30 mins, so if I could choose several time limits to search for a game in at once it would improve waiting times for a partner. Please implement this for the impatient! Thanks lichess
