Describe the bug

I was interested in what this integration did. README wasn't very descriptive so browsing through the code and it's doing I/O inside the event loop. This should be done inside the executor worker thread.

hass-node-red/custom_components/nodered/__init__.py

Line 97 in 256bdda

if not os.path.exists(fullpath):

Change async def -> def and then run `result = await hass.async_add_executor_job(check_files)
