/**
 * Wrapper function designed to be used for callbacks called by setInterval or setTimeout in order to propagate any
 * exceptions thrown in the callback to the main promise chain. It does this by creating a new promise for the callback
 * invocation and adding it to the timerPromises set. The main promise chain can then await
 * Promise.all(timerPromises) to catch any exceptions thrown in any of the callbacks. Note that if the callback
 * completes successfully, the promise is resolved and removed from the set. If it throws an exception, the promise is
 * rejected but not removed from the set, so that the main promise chain can detect that an error occurred and handle
 * it appropriately.
 * @param timerPromises A set of promises representing the currently active timer callbacks.
 * @param callback The async callback to be executed within the timer.
