1619c8b1a1 fix memleak in magick6load 
IM ExceptionInfo were not being freed correctly. This patch
adds a small wrapper function and uses it to allocate and free all IM
exception objects.

Tested with im 6.9 and gm 1.3.

105760be0a seems to work 
though the srgb fallback is not working

```
$ vips icc_import k2.jpg x.v --input-profile=srgb
vips__file_open_read: unable to open file "srgb" for reading
unix error: No such file or directory
icc_import: no input profile
```

perhaps padding issues?

change stops pyramid creation when width or height drop to 1.
