dumb question maybe, but fundamentally what is an event reset? Since `Queue` is just a normal pointer, setting it to `nullptr` seems to just be for bookkeeping in this class and doesn't have any other semantics (like calling the dtor if were a smart ptr)

i'm asking because i wonder if it makes sense to keep the `reset` function always calling `zeEventHostReset`, but then have a new function `clearQueue` or something that only does `Queue = nullptr`, and that new function is called both by `rest` and by whatever callsite doesnt want the `zeEventHostReset` call
