For #406 , add Time constructors from datetimes
...
This was previously an implicit power of `ts.utc()` which was more
difficult for users to find.

Add time array “for” loops in Date arrays section
...
For #390 . There is a single `for` loop illustrated in the previous
section, but users not concerned with leap seconds might easily skip
that whole topic; so let’s also include some `for` loops in the section
on date arrays, where they certainly belong.

More work will be necessary to carry through the extra precision
everywhere, but this is a start that addresses the most visible
manifestation of the previously low precision.

outputs should be more stable now that I’ve pinned the versions of
Python and NumPy.

Rename `JulianDate` to `Time`
...
This improvement removes the apparent redundancy from a statement like:
jd = ts.tt(jd=value)
(why are the raw value and the object both named `jd`, a user might
wonder?) and also hopefully makes it less likely that new users will
think that a `JulianDate` object specifies merely a date but not also a
specific time.

This is a classic case of where I want a short pithy name for a

with due trepidation, I am changing the name to describe its actual
return value. Will anyone be able to stand using Skyfield now?
