[BUG] Index out of range

[LdDl]

Describe the bug
Got next error

panic: runtime error: index out of range [2] with length 0
goroutine 1 [running]:
main.main()
        D:/hp/go/pkg/mod/github.com/!ld!dl/osm2ch@v1.3.0/cmd/osm2ch/main.go:117 +0x1de5

To Reproduce
Just run in on random *.osm.pbf file

Expected behavior
This should not happen

Screenshots
nope

Desktop (please complete the following information):

• Win10
• 1.17
• Public OSM

Additional context
I guess the error is in https://github.com/LdDl/osm2ch/blob/master/cmd/osm2ch/main.go#L117

if _, ok := verticesGeoms[source]; !ok {
verticesGeoms[source] = osm2ch.GeoPoint{Lon: expEdge.Geom[0].Lon, Lat: expEdge.Geom[0].Lat}
}
if _, ok := verticesGeoms[target]; !ok {
verticesGeoms[target] = osm2ch.GeoPoint{Lon: expEdge.Geom[2].Lon, Lat: expEdge.Geom[2].Lat}
}

We need to handle case when .expEdge.Geom has not points in it (actually < 2)
