@turf/kinks returns false self-intersections in MultiLineString features with branches

[ovdleondle]

turf 7.1.0

When a MultiLineString feature has branches (e.g. a river with tributaries, or a street with side streets), kinks module returns self-intersection at the branching point.
For this geojson feature:
{"type":"FeatureCollection","features":[{"type":"Feature","properties":{},"geometry":{"type":"MultiLineString","coordinates":[[[0,0],[0,1],[0,2]],[[0,1],[1,1]]]}}]}

kinks would return a self-intersection at 0,1 coordinates, which is false.

Thanks for reporting this @ovdleondle.

Could it possibly be related to #2722? Would you mind checking to see if the behaviour is correct for v6.5.0?

this appears to be unrelated to #2722:

• this module actually uses its own line-intersect algorithm
• this module, per its description in jsdoc, is intended to report only self intersections

i am not sure that this qualifies as a bug per the documentation within turf but i could be missing some context for what would be expected of a module by this name. this case seems to be behaving as expected just by appearance

Thanks for ruling that out @pm0u. Will take a closer look at this one in due course then.
