If the time is not given in the macro, the device still accepts it and
works properly by setting 10 ms of delay after a key press and 50 ms
between the keys.
Problem is: without this, the RATBAG_MACRO_EVENT_WAIT is not set during
parsing, so we end up having a RATBAG_MACRO_EVENT_NONE between 2 key
events, and the library ends up truncating the macro after the first
RATBAG_MACRO_EVENT_NONE.
