Fix function pointer cast issues

It is undefined behavior in C and C++ to cast a function pointer
to another type and call it that way. This does work in most native
platforms, however, despite it being UB, but in WASM it can fail.

fix default sharpen
...
sharpen with sigma 0.5 was doing nothing, since the new int precision
rules meant that we generated a point-point convolution.
This patch increases the int precision for sharpen, so we now work with
sigma down to 0.5.
Also: restore input colourspace. Previously, the output image was always
LabS (the computation space for sharpen). Now, it transforms back to the
input space. This is more in line with how other operators work.
Thanks 2h4dl for pointing this out.

You must now include vips7 support explicitly with

The old vips7 names, such as `Rect`, were starting to cause problems
with other packages like opencv.

improve rounding in convi intize
...
We were rounding up with ceil() when intize-ing convolution masks.
However, the vector path has a true range of (1.0, -1.0], so a mask with
1.0 as the max (for example) was actually triggering the overflow detector
and falling back to the C path.
Round up with ceil(x + 1) instead, so 1.0 (for example) will be mapped
to 0.5 and won't overflow.
