In history date pickup, adding preconfigured option for 'last 3 hours', 'last 6 hours', 'last 12 hours'

[rdu70]

For data with high granularity (e.g. some temperature, solar production, grid consumption, ... are mesured every seconds or so) it's insterresting to have last hours history quickly available. The shorter available at the moment is 'Today'. It would be nice to add 'Last 3, 6 and 12 hours'. Without that, one has to manualy select the current day only, then start and end time.
If the list is too long it could also be a personalisation option to remove some items.
Anyway, items like 'This year', 'last year' are useless in the context of history as HA keep only limited history in his DB. Those ones are only usefull in the Energy dashboard.
