Describe the bug

Currently the altitude C-chord warning continues to play if the aircraft then enters an overspeed, instead of the overspeed warning starting to play. This also means that the user cannot cancel the C-chord, because the Master Warning button is disabled by the overspeed warning.

I would expect the overspeed to take precedence, although I haven't found any definitive documentation on this. If this is the case then the Master Warning button issue would also be fixed by giving a higher priority to the overspeed warning.

I'm happy to take this issue on and attempt a PR if we think this is the case.

Expected behavior

When the C-chord is playing, entering an overspeed would stop the C-chord and play the overspeed warning for the duration the aircraft is overspeeding.

Steps to reproduce

1. Start the C-chord playing by deviating from the FCU altitude.
2. Enter an overspeed, either outright or by extending the flaps.
3. Observe that the C-chord continues, and the overspeed warning does not play.
