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 arcminutes(), arcseconds(), and mas() methods
...
And while I’m at it, switch to 2-step conversions between radians and
other units. While it was faster to do only a single multiply against a
pre-computed constant like (tau / 360.0), I suspect that two operations
might behave better when the angle is, for example, exactly a multiple
of tau. I should really learn float behavior better (or experiment more).

For #377 , add `position_of_radec()`

This deprecates a poorly designed routine (see the changes to its
docstring for details) and replaces it with a better one.

Extra expense for users who didn’t need it; confusion for those who did.

Separate methods for creating times from JD’s
...
It was awkward to hide the ability to create times from the Julian day
behind the very last argument in the time constructor argument lists.
Let’s start moving in a better direction that makes the ability more
discoverable, and starts to backtrack on one of those awkward situations
where half the arguments to a given method are always useless.
Fixes #181 .

That way, folks will know what project’s site they’ve landed on if they

“Skyfield” that I added to one particular doc’s title a few minutes ago,
but that failed to solve the problem for all other pages.

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.
