Drivers: add an Average Scale option to the Transform Channel driver vars.
Unlike location and rotation, there is a meaningful definition of
overall/average scaling via the total change in the volume. This
adds an option to retrieve that via a single driver variable,
instead of having to use three and an expression.
Using the determinant to compute the volume scaling also allows
detecting flipping due to negative scale - this is impossible
to do via the three variable approach.
The volume_scale functions are added purely for code readability:
'volume scale factor' is easier to understand than determinant.
