References an array of ascending indices. A pair of consecutive indices encode an index range. Another common way to store the same kind of data is to store the start and size of every range separately. Using offsets instead halves the memory consumption. The downside is that the array has to be one element longer than the total number of ranges. The extra element is necessary to be able to get the last index range without requiring an extra branch for the case.
This class is a thin wrapper around such an array that makes it easy to retrieve the index range at a specific index.

Same as above, but skips the debug check that indices are sorted, because that can have a high performance impact making debug builds unusable for files that would be fine otherwise. This can be used when it is known that the indices are sorted already.
