[FR] Hmr assets special handling

Now that HMR is out of beta, i would like to use to it to its fullest.
In my app i want to 'catch" HMR sync events for some files (files in a specific dir) and do a custom reloading from within the app.
To be more precise so that you understand the request. I want to implement HMR for map style files reloading:

• run the app with HMR
• modify the styles files in your favorite text editor
• livesync triggered
• reload map by reloading style

I see there are some way to know that a live sync has been triggered. CAn it be used to do something like this? If so is there any doc/example showing a bit how to do it.

Thanks
