Inclusion of static external data via map matching

[sfendrich]

Implement import of external point data from CSV or maybe database using map-matching to match to graph edges and aggregation to a single value per edge.
This is meant as a replacement for the former way-id-based CSV, Green, Quiet, etc.

• Implement clean Snapping functionality
• Introduce new encoded value
• Implement reading from CSV
• employ map matching
• implement aggregation
• fill new encoded value
• Move ev.DynamicData into com.graphhopper...
• Remove Green, Quiet and CSV Storage
• Refactor Snapping endpoint to use new snapping functionality
• Refactor MatrixSearchContextBuilder to use new snapping functionality
• Refactor Matching-Endpoint to use new snapping
