Enable local data during dev about bos-workspace HOT 1 OPEN

@elliotBraem I'll close this implementation within the next couple of days. Just laying out my plan here so you can correct me if needed:

• I will extend the devJson object to have a field alongside components called data.
• This will be an object with data populated from the folders provided in config.
• It'll be nested based on folder structure, and we will parse txt and json files
• Leaf nodes within the data object will represent files with the following shape: {<filename>: <stringified contents>}
• Set up file watchers for each directory provided in the config, which will patch the devJson.data object with the updated data whenever a file changes
