Support excluding specific hours of a day for a specific day

[zakkak]

Right now we are able to exclude:

1. whole days with timew config exclusions.days.2021_12_24 = off
2. ranges within a day of a week with `timew config exclusions.monday '<9:00 12:40-13:10 >17:30'

But there is no way to exclude part of a single day, e.g. the afternoon of the 24th of December. Intuitively I would expect something like timew config exclusions.days.2021_12_24 = '>12:00' to work.

Thanks for this simple yet great tool :)

Related to #4 where a new syntax for exclusions is proposed. With this, your example would be something like

exclusion = 2021-12-24 >12:00

or maybe

exclusion = 12-24 >12:00

if you have Christmas regularly as a half workday.

Thanks for the pointer @lauft, the proposed syntax looks fine to me :)

I see this is still open, so I'll add another vote for "half day" exclusions on certain dates.
