Add API method to remove duplicate nodes from geometries
...
Removes duplicate nodes from the geometry, wherever removing the
nodes does not result in a degenerate geometry.
By default, z values are not considered when detecting duplicate
nodes. E.g. two nodes with the same x and y coordinate but
different z values will still be considered duplicate and one
will be removed. If useZValues is true, then the z values are
also tested and nodes with the same x and y but different z
will be maintained.
Note that duplicate nodes are not tested between different
parts of a multipart geometry. E.g. a multipoint geometry
with overlapping points will not be changed by this method.
The function will return true if nodes were removed, or false
if no duplicate nodes were found.
Includes unit tests and a processing algorithm which exposes
this functionality.

[FEATURE][processing] New 'assign projection' algorithm
...
This algorithm assigns a new projection to a vector layer.
It creates a new layer with the exact same features and
geometries as the input one, but assigned to a new CRS.
E.g. the geometries are not reprojected, they are just
assigned to a different CRS.
This algorithm can be used to repair layers which have
been assigned an incorrect projection.

[FEATURE][processing] Add 'Join by location (summary)' algorithm
...
Like the main Join Attributes by Location algorithm, this algorithm
takes two layers and combines the attributes based on a spatial
criteria.
However this algorithm calculates summaries for the attributes for
all matching features, e.g. calculating the mean/min/max/etc.
The list of fields to summaries, and the summaries to
calculate for those, can be selected.

Improvements:
- transparently handle different source/join CRS
- added option to create output feature for EVERY joined

- added option to select joined fields to take
- optimised performance of algorithm
The previous option to create a summary of joined features has been
removed, and will be moved to a separate 'Join by location (summary)'
algorithm.
