b6e35428e2 Optimise calculation of envelopes for MinimumBoundingGeometry alg 
It's more efficient to calculate these on the fly, rather then
collecting all geometry points and then calculating.

83affdc7f5 [FEATURE] New processing algorithm "minimum bounding geometry" 
This algorithm creates geometries which enclose the features
from an input layer.

Numerous enclosing geometry types are supported, including
bounding boxes (envelopes), oriented rectangles, circles and
convex hulls.

Optionally, the features can be grouped by a field. If set,
this causes the output layer to contain one feature per grouped
value with a minimal geometry covering just the features with
matching values.
