getframes 2.3.0

Fixed

• MoffatPSF, EllipticalGaussianPSF and AiryPSF no longer put light that
  falls off the frame back onto it. They normalised their stamp after
  clipping it to the frame, so a source on the edge column deposited its full
  flux instead of the part that lands on the detector (a Moffat star centred on
  column 0 kept 100% of its light, where GaussianPSF correctly keeps about
  half). The stamp is now normalised before clipping, which follows the AO stack
  convention that light lost at a detector edge is lost, not renormalised
  (aocore CONVENTIONS 3.3). Sources wholly inside the frame are unchanged.

Changed

• Generic primitives now come from aocore. getframes is part of an
  adaptive-optics stack whose shared conventions and primitives live in
  aocore, now a core dependency
  (aocore>=0.1.2,<0.2). noise.block_sum is aocore.block_sum, re-exported
  so existing imports keep working; it accepts everything it did before and now
  also takes a (fy, fx) factor and leading batch axes, and raises a clear
  ValueError for a factor below 1 or a shape that does not divide (previously
  a bare reshape error, or a ZeroDivisionError for a factor of 0).
  Frame.binned sums through it. AiryPSF and Thermal take their radians per
  arcsecond from aocore.ARCSEC_TO_RAD, and Vignetting its centred grid from
  aocore.coordinate_grid. Every output is bit-for-bit unchanged.

Added

• Conformance tests (tests/test_conformance.py) run the
  aocore.conformance checks that apply to a detector package: every PSF model
  deposits unit flux, a source at (n - 1) / 2 and the vignetting pattern are
  centred on the optical axis for odd and even windows.
