rotation_center_calibration_start(sample_type="isolated") didn't match the
xrayeye_* naming convention used by the other X-ray eye entry points, and
the sample_type string enum was easy to forget (both the parameter name
and its accepted values). Split into two entry points instead:
lamni.xrayeye_rotation_center_calibration_isolated(keep_shutter_open=False)
lamni.xrayeye_rotation_center_calibration_extended(keep_shutter_open=False)
Both delegate to a shared _xrayeye_rotation_center_calibration() private
helper (single copy of the KeyboardInterrupt cleanup). Updated the user
docs to match; XrayEyeAlign.find_rotation_center()'s own sample_type
parameter is unchanged since it's internal shared implementation, not
what was being objected to.
