smurf: Deal with uninitialised SCUBA-2 header
Unfortunately a broken SCUBA-2 FITS header is a header filled with
zeroes rather than no header or a header with spaces. This meant
that we did end up with a header hash but it didn't have any
relevant cards in it. We now count to make sure we have cards
although we could force a check for INSTRUME.

hds: fix problem with int arithmetic overflowing
this was revealed when using NDF sections on large images that required the data to be sliced
there could be more of this kind of issue to find

smurf: Interpolate GAI model properly across bad bolo-blocks
Previously, there could be discontinuities in the gain and offset values
at the edges of bad blocks.
Thought this may have been a cuase of the spurious bolometer tracks that
appear at high iterations, but it seems not to have fixed the problem. It
needed doing anyway.
