Camera Settings 0.3.0rc1 - HLS Support for Preview

I've released a new release candidate for the Camera Settings plugin. The only change is that the preview should now work for HLS streams as well.

If you are using HLS and this plugin, please update to this RC by selecting the 'Release Candidate' channel for it in the Software Update page in the OctoPrint settings:

If you are using HLS and aren't using the Camera Settings plugin: why not!?

I don't expect any issues, but if this new feature isn't working properly for you, please let me know here or open a new issue on the github repo.
