Fix UBSan errors (#1948) 
* Ensure UBSan exits with a non-zero code on error

* Avoid misaligned member access in mosaic_fuzzer

* Add missing VIPS_CLIP in scRGB2sRGB/scRGB2BW

* Fix UBSan error in flatten

By using saturated casts for the int types (copied from vips_cast).

* CI: ensure fuzzer log is printed on error

* Avoid UB in heifload

* Revert flatten change

I could no longer reproduce this with clang 12 locally.

* Indentation fixes [skip ci]

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.

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.

3ea72c286e improve fuzz targets and oss-fuzz integration 
It replaces current fuzz setup with 5 new fuzzers integrating them with
top-level Makefile. It now supports multiple fuzzing engines and Google's
oss-fuzz. By default, the fuzzers are linked against an standalone runner to
easily reproduce bugs.
