A layer graded with Apply Color LUT or Lumetri's Input LUT and Look was
cached by the parameter text alone, so the same frame kept showing the old
LUT from memory and from the disk cache after the file changed. A layer's
cache key (and the key of a layer reading it, through a precomp too) now
holds each LUT file's size and modification time, and a render lists the
LUT files it read, so a frame kept on disk made with an older file is not
used.
