Date-fns: Support eachYear eachMonth eachWeek eachHour eachMinute

[amazing-gao]

Hi, team.
eachDay is a very convenient function under some situation. but it's not comprehensive, i think eachYear,eachMonth,eachWeek,eachHour and eachMinute will be very useful too.
Is there any plan for this?
Thanks.

@BiteBit could you write a more complete proposal with example inputs and outputs?

At the _moment_ the date-fns team has no throughput for that, but PR(s) is welcome!

Any changes for v2?
I found an implementation in date-fns codebase, but apparently it isn't available anymore in v.2:
