------------------
* Add dimage (Blanton's) simplexy and refinexy for centroiding if wanted
* Add nudge option for centroiding based on CCD static distortion model
* Default to 33 term ZB basis and nudge centroiding for FVC
* Fix a bug in which the object epoch for an ``ICRS`` coordinate would not change when ``ICRS.to_epoch()`` was called.
* Tweaks to ``FVCTransformLCO`` parameters based on telescope data.
* Moved astrometry.net and guider fitting tools from ``cherno`` to ``coordio.guide``.
* Added a ``coordio.extraction.sextractor_quick()`` function for simple extraction with background subtraction using ``sep``.
* Change ``defaults.FOCAL_SCALE`` to 1. It may be removed in the future.
