[dependabot]

Bumps skyfield from 1.35 to 1.36.

Changelog

Sourced from skyfield's changelog.

v1.36 — 2021 January 26

• Tweaked several lines of code that build NumPy arrays to avoid a new deprecation warning Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. NumPy no longer wants to accept a simple constant like 0.0 where the resulting array needs a whole row of zeros. [#536](https://github.com/brandon-rhodes/python-skyfield/issues/536) <https://github.com/skyfielders/python-skyfield/issues/536>_

• Added :meth:~skyfield.positionlib.ICRF.hadec() position method that returns hour angle and declination. [#510](https://github.com/brandon-rhodes/python-skyfield/issues/510) <https://github.com/skyfielders/python-skyfield/issues/510>_

• The default str() and repr() strings for geographic positions have been streamlined, and no longer raise ValueError when elevation is an array. They now show simple decimals instead of splitting degrees of longitude and latitude into minutes and seconds; always show elevation, even if zero; properly format NumPy arrays; and abbreviate long arrays. [#524](https://github.com/brandon-rhodes/python-skyfield/issues/524) <https://github.com/skyfielders/python-skyfield/issues/524>_

• Fixed :meth:Angle.dstr() <skyfield.units.Angle.dstr> and :meth:Angle.hstr() <skyfield.units.Angle.hstr> to return an array of strings when the angle itself is an array. [#527](https://github.com/brandon-rhodes/python-skyfield/issues/527) <https://github.com/skyfielders/python-skyfield/issues/527>_
