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

more vips_resize() tuning
...
now we have better tuning for the anti-alias blur, we can increase the
amount we shrink by and reduce the amount we affine by
this gives a noticable speedup

much better handling of arrayimage cli args
...
we were not setting the access hint on arrayimage args, so
arrayjoin "$(echo *.jpg)" x.tif[bigtiff] --across 10
would open all the jpg images to memory, usually, in random mode
now arrayimage args see the operation's access hint (seq in this case),
for much better behaviour
also, we allow any whitespace as an arg separator in arrayimage from
string
