Add XYDataImageAnnotation support

This one is hitting a road block and so time-gapless XYDataImageAnnotation is not going to be supported.

It's believed we need to somehow map the time domain width to a spanning discrete number of numeric indices emulating the width but the time domain width can be fractional in the discrete index domain. Instead of providing a best fit guess that could leave users wanting, I'm going to leave this capability unimplemented.

One could perhaps extend the XYDataImageBuilder class to override its mapXToTimeIndex() method and attempt writing their own.

Perhaps a convenience nearest neighbor implementatation could be written but I don't know what's suitable here. It might be best to use the new XYImageBuilder instead.
