Access to DWT timer?

SDK Development Discussion

According to my notes @Marc said May 2021:

In Lua we've got playdate.getElapsedTime() and playdate.resetElapsedTime() which allow for measurement with microsecond accuracy via the DWT Cycle Counter. It looks like we don't have it exposed in the C API at the moment, but can probably fix that for 1.1 as well!

But given your request and playdate.getElapsedTime (high resolution timer) only accurate to milliseconds (Lua) it looks like something may have gone awry.
