7ef5631d6b [FEATURE][processing] Line substring algorithm 
This algorithm returns the portion of a line (or curve) which falls
between the specified start and end distances (measured from the
beginning of the line).

Z and M values are linearly interpolated from existing values.

526e590c8d [FEATURE][processing] Add "raster pixels to points" algorithm 
Refactor the existing "raster pixels to polygons" algorithm and
create a new "pixels to points" algorithm, which creates a point
feature at the center of every pixel. nodata pixels are skipped.

97e0db6245 [FEATURE][processing] Filter Vertices by M and Filter Vertices by Z algorithms 
Adds two new algorithms, for filtering line/polygon vertices by their
M or Z values. A minimum and maximum M/Z value can be entered, and
if the vertices fall outside these ranges they will be discarded
from the output geometry.

Both min and max filter value can also be data defined, so can
vary per feature.

34b9d39b27 [FEATURE][processing] K Means clustering algorithm 
Adds a native k-means clustering algorithm.

Based on a port of PostGIS' ST_ClusterKMeans function, this
new algorithm adds a new cluster ID field to a set of input
features identify the feature's cluster based on the k-means
clustering approach. If non-point geometries are used as input,
the clustering is based off the centroid of the input geometries.
