getPropertiesAtLength in a bezier part returns x coordinate for both x and y

[logi]

There is a pretty obvious error on this line:

https://github.com/rveciana/svg-path-properties/blob/7f2466ca0a9097cbe7f6bcfb76c5a69a761cff08/src/bezier.ts#L101

I'm not set up for typescript development so I'm not in a hurry to make a PR for this.

The jest tests in my project to verify that the library doing the wrong thing:

describe('svgPathProperties', () => {

    const spp = require('svg-path-properties');
    const pathStr = 'M224,32C153,195,69,366,76,544C77,567,97,585,105,606C133,683,137,768,175,840C193,875,225,902,250,932';

    it('returns point at length', () => {
        const pathProps = spp.svgPathProperties(pathStr);
        const point = pathProps.getPointAtLength(300);
        expect(point).toEqual({
            x: 111.7377391058728,
            y: 310.0179550672576,
        });
    });
    it('returns tangent at length', () => {
        const pathProps = spp.svgPathProperties(pathStr);
        const tangent = pathProps.getTangentAtLength(300);
        expect(tangent).toEqual({
            x: -0.29770950875462776,
            y: 0.9546565080682572,
        });
    });
    it.skip('returns properties at length', () => {  // Fails because of https://github.com/rveciana/svg-path-properties/issues/43
        const pathProps = spp.svgPathProperties(pathStr);
        const props = pathProps.getPropertiesAtLength(300);
        expect(props).toEqual({
                x: 111.7377391058728,
                y: 310.0179550672576,  // This is incorrectly equal to 111.7377391058728 
                tangentX: -0.29770950875462776,
                tangentY: 0.9546565080682572,
            },
        );
    });

});

I'll take a look, thank you.

Just to be obvious, the second xs passed to this.getPoint should be xy. Although I'd probably replace every xy in that file with ys as well.

Solved and npm version bumped. Thanks a lot
