Range address mapper that maps a set of original ranges to a set of remapped ranges, where a specific range is of the same size (original and remapped), only with an offset.
It's useful for cases where memory is mapped to two different locations

This function does the actual remapping of one address to another.
It is pure virtual in this case to to allow any implementation required.

This contains a list of ranges the should be remapped.
It must be the exact same length as remappedRanges which describes what manipulation should be done to each range.
