following links in [examples/README.md](https://github.com/mifi/editly/blob/master/examples/README.md) are wrong: [customCanvas.js](https://github.com/mifi/editly/blob/master/examples/customCanvas.js) [customFabric.js](https://github.com/mifi/editly/blob/master/examples/customFabric.js) [fabricImagePostProcessing.js](https://github.com/mifi/editly/blob/master/examples/fabricImagePostProcessing.js) It's mistakenly using a .js extension, but these are all .ts files.
