Snapshot class
Manages the creation of a single snapshot file in a context where multiple async functions could be trying to use and/or create it.
To use:
var s = new Snapshot(...);
if (s.needsSnapshot) { // create s.snapshotFile, then call: s.snapshotCompleted(); } else { await snapshotValid(); // use existing s.snapshotFile; }
