There is, sort of. The JPEG 2000 specification supports up to 214
channels, each with 1-38 bits; gray or color. That's a lot more than
you asked for but should hold the fort for awhile.
I think the reason we haven't seen more of it is that folks are afraid
of legal tangles. Many of the math algorihms have been patented by
others. Most of those patents have been cleared with their owners but
"most" and "all" are two different things.
