`FromDhall`/`ToDhall` for types from `time`?

[amesgen]

I am not sure whether this has been discussed before, but what about implementing FromDhall/ToDhall for various types from time, like Day, TimeOfDay, LocalTime, ZonedTime, UTCTime, now with #2247?

Whoops, this is an oversight on my part! Yeah, this is a great idea and it should be easy for me to add

Fix is up here: #2294

Thanks for the instances for Day, TimeOfDay and TimeZone! I created #2300 to also add instances for LocalTime/ZonedTime/UTCTime (if that is desired).

Would you consider also adding DayOfWeek (as the obvious 7-element enum)? I've found this useful in some projects.

@georgefst: I opened a PR to add isntance for DayOfWeek: #2413
