WMTS multidimensional histogram calculation failures against coverage views, and bucketing has overlaps

Description

Running a request against a multi-band coverage view multiplies by the number of bands the result (e.g., have one image, the histogram reports 10), plus, the buckets for the histogram are inclusive of both start and end value, which causes some issues in histogram calculation (e.g., data spread over two days, at midnight of each day, would be assigned fully to the first day, and none to the second)
