John Cupitt cb1634dd31 block fuzz data over 100kb
Many codecs can take a huge amount of time attempting to read large
random objects. jpeg_read_header(), for example, can take ~10s on a 1mb
of random data.

Ignore fuzz objects over 100kb.

John Cupitt 1de458556a try adding a file fuzzer
oss-fuzz normally fuzzes with memory buffers, but a lot of the libvips
loadres, especially CSV and PPM, only work from the filesystem.

This fuzzer writes the oss-fuzz buffer to the FS, then fuzzes that.
