+/**
+ * When rapidly saving files atomically a couple of situations can happen:
+ * - The file is missing since the external program has deleted it by the time we've gotten around to reading it from the earlier save.
+ * - The file is being written to by the external program by the time we're going to read it and is thus treated as busy because a lock is held.
+ *
+ * To work around this we retry reading the file a handful of times with a delay between each attempt
+ *
+ * @param {string} path
+ * @param {number} tries
+ * @returns {Promise<string | undefined>}
+ * @throws {Error} If the file is still missing or busy after the specified number of tries
