fc1e609f44 libheif: expose speed parameter (currently AV1 compression only) 
Supports both aom and rav1e encoders by limiting to a 0-8 range.

(The rav1e encoder accepts speed values of 9 and 10 but these
use 64x64 blocks more suited to video than images.)

0ee8b1e844 improve seek on pipes 
There were a few issues in VipsSource around seeking on pipes. With this
patch, EOF detection is better, and pipe sources automatically turn into memory
sources when EOF is hit.

237604bb07 revise heifload EOF detection 
VipsSource used a unix-style model where read() returns 0 to mean EOF.
libheif uses a model where a separate call to wait_for_file_size()
beforehand is used to check thaht the read will be OK, and then the
read() is expected to never fail.

We were trying to put EOF detection into libheif read(), but that's not
the right way to do it. Instead, test for EOF in wait_for_file_size().

passed within vips_fractsurf. This was discovered when running
