Approving this to address the issue where LED state is not synchronized at init. There are a couple of other issues in existing code that need to be addressed (e.g. set_key_toggle_state is not actually updating state to endpoint), but I will work on those as part of a separate PR to refactor LED handling a bit.

@joschock, can you please file a bug in the repo to track those?
