renfe: generate shapes properly and consistently

- Update OSRM container to use ALL SPAIN (sorry, Trencelta)
- Generate a shape per trip (no trying to reuse, since trains that change stop sequence got wrong shapes)
- Add more position corrections for FEVE
- Run separate generators for FEVE and Renfe, since sometimes OSRM would pick the one that shouldn't and generate a wrong shape
- Add a debug script to generate a trip's visualisation from GTFS, since I was about to lose my mind debugging this pile of crap
- Update README (before starting anything else)

Time spent: ca. 6 hours

Closes #1
