Support for UltraHDR #481
Description
libvips is adding support for UltraHDR, the "new" standard for backwards compatible HDR photography, already produced by milions of phones right now.
As such it would be good if bimg and therefore imaginary would support this out of the box as they have to support that using their higher-level API explicitly.
A release with that enable will be coming soon: libvips/libvips#3799 (comment)
This would probably outright fix h2non/imaginary#438 as it would probably just work if the higher level API support it, as I understand it.
