Create a SkyWcs from the telescope boresight and detector geometry.
A typical usecase for this is to create the initial WCS for a newly-read
raw exposure.
Parameters
----------
visitInfo : `lsst.afw.image.VisitInfo`
Where to get the telescope boresight and rotator angle from.
detector : `lsst.afw.cameraGeom.Detector`
Where to get the camera geomtry from.
flipX : `bool`, optional
If False, +X is along W, if True +X is along E.
Returns
-------
skyWcs : `lsst.afw.geom.SkyWcs`
The new composed WCS.
Raises
------
InitialSkyWcsError
Raised if there is an error generating the SkyWcs, chained from the
lower-level exception if available.
