Drop detector type and quad flag from the gap pixel API

insert_gap_pixels and gapped_shape only used the detector type to reject
anything but Jungfrau and Eiger, and the quad flag only to shrink the
module width to 512. Both Jungfrau and Eiger use 256x256 pixel chips in
1024x512 modules, and an Eiger quad is 512x512 pixels, so its only chip
boundaries are at pixel 256 and the module width never matters. The
layout is now fixed and both functions take just the image, its ROI and
the GapPixels configuration, in C++ and in Python.

RawFile keeps rejecting gap pixels for other detector types with
std::invalid_argument, now checked in the reader instead of the layout.
