AttributeError: 'GGPOEvent' object has no attribute 'frames_ahead'

[StormyNight2020]

I receive this error while running my simple game inspired by the example game included with this repo. During my cbk_on_event callback, I'm trying to handle GGPO TIMESYNC events just as the example game suggests in order to idle the session for the given number of frames:

if event.code == ggpo_py.GGPOEventCode.GGPO_EVENTCODE_TIMESYNC.value:
self.session.idle(round(1000 /60 * event.frames_ahead))

The reference to event.frames_ahead is causing the issue. I'm not familiar with pybind11, but from what I can tell from py_ggposession.cpp in the src folder, all of the other GGPOEvents with specific attributes are binding them (like SYNCHRONIZING_WITH_PEER) except for the TIMESYNC event. Perhaps adding the binding for the frames_ahead attribute would do the trick?
