Hydration indicators (Emojis) for stats command should scale to length of time requested.

over longer timescales than a day this makes pretty simple sense, a direct linear scale will work.

for time periods shorter than a day it starts to get rediculous calling someone dehydrated when they've simply not drank in the past hour.

one suggestion for this was to just give those with anything logged in the time segment a thumbs up, and everyone else a neutral emoji.

I think 6 hours is probably the cutoff where a linear scale from 2L/day starts to no longer make sense
