Manual revision of manually simplified data

[anastassiavybornova]

Issue: manual simplification was done with "old" original data (contaning service roads). the "new" original data (see here: https://github.com/uscuni/simplification/tree/main/data ) has no service roads. so the manually simplified data needs to be checked against it. as a helper we have gpkg files (deltas.gpkg) for each city with a hexagon grid (see here: https://github.com/uscuni/simplification/tree/main/revision , generated by the notebook here: https://github.com/uscuni/simplification/tree/main/notebooks/manual-revision: )

the columns "edge count delta to verify", "node count delta to verify", and "edge length delta to verify" have true/false indicating for each hexagon whether there is a negative value for the metric (ie whether original minus manual is negative) , and the column "to verify total" counts the total number of negative values.

the task is to check for each city those hexagons which have a "to verify total" > 0, and either:
a. correct the manual simplification data OR
b. mark the hexagon as non-problematic

Finally uploaded the parquets/gpkgs of revised manual simplification and hexagons to branch hexagon-revision.

Also added a new column status to hexagons with values clean, fixed and non-problematic; I marked all of the hexagons accordingly. Wuhan was the most problematic again as per tradition.

The majority of the non-problematic hexagons contain manual simplification identical to the original data with only a minor difference in edge_length_delta. Other than that I hopefully got rid of all service roads.
