Add line and polygon drawing support

[kochis]

• Add support for drawing lines and polygons
• Support for polyline rendering
• Introduces a new RadarFeature class for adding GeoJSON features to the map.

Usage:

// adding a polyline to the map
const polyline = 'iyeulAveaclCuVfw@aA|CuAlEgj@teBm@jBs@|BbBjA~XzRdFnDfBlA`A{C`@mA~h@icBfAmD`A{Cff@c|A|A{E|BZfJrAh[lEhC^dBThMdBnTtCd@LzBx@|BjA^RhZnUzBdB`BtAl\\zWvAjAlBzA|UjRfEhD`ClBhRfOlCxBjBxAhBxAxKzItNhL|BhBnB|Af]rXnB~A|AnAn[fWbAv@~ArAzBfBxStPbInGtB`BlBzA~b@l]bAx@d@\\jBxAjMdKTPxGlFnJvH|StPnCxBhFbEr@{EfEeYvCyRf@kD\\{BBUtC}RfAoFbAcFpDsNl@_Cl@aCfLcd@r@sCn@cC`Lsc@p@kCl@aCjE}P`E}Od@iBz@{DrD`A|JxCxWdFxc@fLzIzBzL~C~Bj@dAXlg@rM~Ab@pA^|`@pLp@RtBl@bBf@xEpAjQ`FtBl@xF~AjEjAtIbCxGMzWjIhCv@jBl@ju@pUnCz@pCdAvRnIfUpJlV~KtBbAlB~@l`@|SvBhAXNjCvApLnGxBlAnFtCnGeEbZyQ~G}E`B}AhBsBfByBnFkH|AiBzAeBzAcB|A{AdB}ApBwAhCyAfCkApVwKbh\\qjOjBKhBWdCu@zDgBvAi@xAi@dBc@`BQpAGrAFvAVtAp@lAz@lAvA~@hBj@|BXdCFtBIhCWtBe@`By@|AeArAm@`@e@Rs@PyANoB@yAL}AT_BXyBQ}IW_Um@aQUqAHcBTyBf@_Dt@{Ad@uAj@}CrAuR|IoCnA\\gUBiBmCBoDGaIOkL[yNWeB@gBBcC?ao@iBwBEyBGkYs@}HQoAEeBEua@aAyAEyGQ';

const lineFeature = map.addPolyline(route, { 
  id: 'route', 
  precision: 6 
});

lineFeature.on('click', ({ feature, originalEvent }) => {
 // do something when clicking on line
});



// adding a polygon to the map
const geojson = {"type":"Feature","properties":{},"geometry":{"type":"Polygon","coordinates":[[[-73.95820498349376,40.80026256420331],[-73.9816545434309,40.76824212209061],[-73.97283590550576,40.764244806438285],[-73.94918592197929,40.79677293396304],[-73.95820498349376,40.80026256420331]]]}}

const polygonFeature = map.addPolygon(geojson, { 
  id: 'polygon',
  paint: {
    'fill-color': '#FF6F00',
    'fill-opacity': 0.3,
  },
});

polygonFeature.on('click', ({ feature, originalEvent }) => {
   polygonFeature.remove(); // remove feature from map
});


// fit the map to all features
map.fitToFeatures({ padding: 20 });

// remove all features from map
map.clearFeatures();
