Sort fish by next 24 hours rarity first

[icykoneko]

I was discussing this with others in Fishcord, but I think it'd be useful to have a sorter that uses a fish's uptime over the next 24 hours to sort by. Any fish not up within 24 hours, would be sorted by overall rarity instead,, using the binning approach.

The idea being, if I could fish all day long, but there's two very rare fish up, and the slightly less rare fish will only be up once today, while the more rare fish is up twice today, I would like to see the first one listed on top. When I refer to rarity, I'm using the overall rarity method (the 10 window uptime calc).
