Sdss-coordio

------------------

* Updated release action in GitHub to build wheels for manylinux and macOS.

------------------

* Add ``FVCTransformAPO`` class.
* Change the base URL for the IERS bulletins.
* Pass the ``fpsScale`` parameter to ``wokToFocal`` when creating focal coordinates from wok coordinates.

------------------

* Add ``fpScale`` parameter to adjust the scale of the focal plane. Default value is 0.9998.
* Modify default behavior between focal plane and wok to assume a flat wok.

------------------

* Add ``fiberAssignment`` to ``Calibration``.
* Add new implementation of ``tangentToPositioner``.
* Add GFA coordinates to calibrations.
* Add plate scale defaults for APO and LCO.

----------------

* When ``Calibration`` does not have any files, the data frames are set to empty instead of ``None``.

----------------

* Use measured alpha and beta offsets when transforming from tangent to positioner.
* Replace error in ``iauPmsafe`` with warning.
* Add ``RoughTransform`` and ``ZhaoBurgeTransform`` (11).
* Undo changes to ``wokToTangentArr``. Reverted to only supporting one holeID per array (11).
* Add a ``Calibration`` class to store all active calibrations, allowing for concatenation of different site calibrations (12).
