Title: apps: added ociolutimage, used to generate / extract 3dluts from images.

ociolutimage is a prototype of a command-line tool, to generate and extract 3dluts from images.

There is a barebones prototype, with known improvements / deficiencies:
- Only supports writing .spi3d 3d-luts. (other formats need an ociobakelut post-transcode step)
- Relies on code copied from the internal library. This should be added to the external interface in an upcoming OCIO version.

The current use-case for this tool is to generate the aces rrt 3dluts, in conjunction with ctlrender:
