feat: Add rrweb replay config

[pulpdrew]

This PR adds a replay item to the HyperDX config which is passed through to rrweb, allowing for users to pass custom callbacks for DOM mutation events:

    HyperDX.init({
          apiKey,
          service,
          recordCanvas: true,
          replay: {
            hooks: {
              mutation() {
                console.log('DOM mutation observed');
              },
            },
          },
        });

canvasMutation is available, but it appears rrweb 1.1.3 does not actually call the canvasMutation callback on all canvas events. A larger upgrade to rrweb v2 may be necessary to improve canvas support.
