clean up foreign
...
various cosmetic changes:
- pngsave_buffer now uses Write, not WriteBuf, same change for
radsave_buffer
- move C wrappers out to class defs from foreign.c
- use g_free() not vips_free() for buffer free from low-level savers
- fix var names in some comments
- various style changes for radiance.c

and on image close, if more than 100% of the pixels have been
calculated, you get a warning

make python bandrank() work like bandjoin()
...
we had a custom wrapper for bandjoin(), but bandrank(), a function with
an almost identical interface, did not ... this was confusing
bandrank() now has a custom wrapper too ... this breaks API
unfortunately, but hopefully very few people were using this thing and
it's better to make this change as soon as possible

better handling of cast+shift for non-int formats
...
before, im.cast(uchar, shift = true) where im was float and tagged as
rgb16 would not shift the image, since it's unclear how much to shift a float
type by
now we do two casts: first, we guess the numeric range from the
interpretation, so rgb16 would be ushort, so we cast float->ushort;
second, we cast to the target type and do the shift on the way
see https://github.com/jcupitt/libvips/issues/397

stencil position elsewhere. The right way to do centre convention is to offset
