ImageMosaic supporting multiple WKBs as overviews masks

Description

ImageMosaic already supports multilevel raster masks: a mask for each overview, stored within raster file, as binary validity mask. It also supports sidecar files storing a single geometry mask for granule.
It would be great to also support multiple sidecar files (such as a WKB geometry for each overview)
