	The SAGA version of this algorithm is of limited use in QGIS, because the volume calculated is embedded only in the SAGA terminal output. This prevents it being saved to a file, or reused within a model as an input to a later model step. It's also very user-unfriendly, because users must know to manually scan the algorithm log to find the SAGA output. Given that the maths here is trivial, this commit ports the algorithm across to be a native QGIS c++ algorithm. The algorithm duplicates the SAGA alg 1:1, but outputs the volume (and area) to either a HTML report, or a vector table. Additionally, the outputs are exported as numeric outputs from the algorithm, allowing them to be re-used within models. (It's also considerably faster, because it avoids the forced conversion to SAGA raster format) Fixes #8607 (properly, even though that report is closed)
