Fix #155822: Out of bounds buffer read when writing AVIF image format

Browse source 
Saving AVIF was reading past the buffer bounds for 8bit images,
workaround the bug by re-allocating a buffer with the necessary
padding to avoid the error.

This has been fixed up-stream, the workaround can eventually be removed
when we drop support for older OIIO versions.
