Revise power network generation #119

Open tomalrussell opened 1 year ago

Look again at preprocess steps for speed:

[ ] try defining box (aka slice) grid in a way that snail can quickly split gridfinder lines and GPPD powerplants to boxes
[ ] try raster reproject/mask operation to get population with targets; or snail slice target geoms - whether zonal-statistics or polygons-from-raster is slower?

Changes to output:

[ ] split transmission lines on country boundaries, record "interconnector" nodes in a way that it's possible to remove/disable those connections from the network
[ ] clip transmission lines to box/slice boundary, with artificial connection nodes on edge recorded in connector .json output
