possibility to align (multi-) polygons to (multi-) lines?

[dieuska]

At the moment brdr supports in aligning thematic (multi-) polygons to reference (multi-) polygons.
In some cases it could be useful to align these thematic polygons to line geometries

[dieuska]

As we have a snapping (tracing)-method in the geometry_utils.py. this could be used (with adaptions) for also aligning (Multi)Linestrings,?

[dieuska]

basic working logic is added to also align (Multi)Points and (multi)linestrings to reference borders. This still has to be:

• cleaned up:
• Checking the logic when using it in a predictor/evaluate-function
• taking more parameters into account (fe od_strategy)
• adding tests
