feat(road-comparison): add indicator for road comparison

[Gigaszi]

Description

Adds an indicator which queries the length of road data in an AoI based on Microsoft Data and how much of it is covered by OSM data. Based on this ratio a quality estimation is made.

For this, the OQAPI DB is restructured, which is why with this PR also the name of the DB table for the building comparison indicator was changed

Preprocessing and Calculation Done. All tests are done and not failing.
Figure: current figure (taken from old attribute completeness indicator) was adapted to work with plotly and to be storeable as dict. However, not yet changed to other possible plot types. If another plot type than type 'pie' is used, the last test must be adapted

To use this indicator in the dashboard as long as no data (including coverage) is on the server, the coverage and preprocess function are commented out and mocks written instead. Therefore, test are failing at the moment as some check the result when the indicator is queried outside of the coverage area, but atm. it is mocked to always be within he coverage. Once data is on the server, remove the two lines of mock return in the functions and comment the real function content back in. With this, the tests should not be failing anymore
