Custom paths

[bitttttten]

Is your feature request related to a problem? Please describe.
I would love to be able to give my own path generator script to react-sketch-canvas. For example on https://www.tldraw.com/ they have a few different brush types that use a custom generator to produce the SVG. It would be great to be able to drop in our own pens to react-sketch-canvas.

Describe the solution you'd like
Perhaps a way to pass a callback that receives the current path as an array and takes back an SVG path?

Thinking out loud here although I can imagine a callback something like the below:

<ReactSketchCanvas
      style={styles}
      width="600"
      height="400"
      strokeWidth={4}
      strokeColor="red"
      getSvgPathFromPoints={(points: Vec2d[]) => `M${points.map(getPoint)}`}
    />
