booleanPointInPolygon: ignoreBoundary option is ambiguous

• turf version: 6.5.0

the result of the following code is false false while point (1.5,1.5) is mathematically on the boundary of the polygon.

const pt = turf.point([1.5, 1.5]);
    const poly = turf.polygon([[
      [0, 0],
      [1, 0],
      [2, 1],
      [1, 1],
      [0, 0],
    ]]);
    const a = turf.booleanPointInPolygon(pt, poly, { ignoreBoundary: true });
    const b = turf.booleanPointInPolygon(pt, poly, { ignoreBoundary: false });
    console.log(a);
    console.log(b);

I guess you mean something else by 'boundary' and perhaps you mean vertices defining the polygon. It sounds ambiguous by the way.

Start by reproducing the JavaScript snippet at the booleanPointInPolygon entry point and inspect how ignoreBoundary is interpreted for the reported polygon. Done means the boundary semantics are unambiguous and the behavior for both option values matches that definition, with coverage for the reported case.
