Carto edits to lines to reduce crossings

[oobrien]

Will make some carto edits to the lines, to reduce unecessary (even if true) crossings.

Definitely:

• Bakerloo crossing Circle/District just east of Paddington Praed St - make it a touch at the station instead.
• Jubilee crossing Circle/District/Met east of Baker Street - make it a crossing at the station instead.
• Victoria crossing Northern just east and just west of Euston - making it a touch at the station (shift the Northern)
• Central crossing Overground twice just north of Liverpool St - shift it NWwards.
• Central crossing DLR twice west of Stratford - shif tit Nwards.
• Elizabeth crossing DLR and Central west of Stratford - shif tit Nwards.
• Elizabeth crossing DLR just west of Royal Victoria - shift it Nwards.

Maybe:

• Shift Piccadilly/Victoria between Finsbury Park and Manor house to eliminate double-crossing.
