c6a91dab09 [FEATURE] Use native interpolate point method instead of GEOS method 
Because:
- Exactly follows curves and doesn't require segmentizing input geometry
- Also interpolates z/m values if they are present in input geometry
- Is faster

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.

93ee06247d Count and report progress based on expected total 
Algorithm appears to freeze without progress while `extent_engine.intersects(geom.constGet())` returns false. 

This keeps the progress bar continuous and smooth, even if the feature ends up not being added.

(noticed this because the algo hangs for 2 mins while processing a large dataset which I think is outside the extent somehow. None of the points going in. No apparent progress.)

63fd4bab2a [processing][FEATURE] Store models inside QGIS project files 
Allows processing models to be stored inside QGIS project files,
so that opening the project makes that model available.

Some models are so intrinsically linked to the logic inside
a particular project that they have no meaning (or are totally
broken) outside of that project (e.g. models which rely
on the presence of particular map layers, relations, etc)

This change allows these models to be stored inside that project,
avoid cluttering up the "global" model provider with models
which make no sense, and making it easier to distribute a single
project with these models included.

Models are stored inside projects by clicking the new "embed
in project" button in the modeler dialog toolbar. Models can be
removed from a project from the model's right click menu in the
toolbox.

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.
