From 67cc8d8e99b73adc00b47be0b4749b020714ab9a Mon Sep 17 00:00:00 2001
From: Herbert Wolverson <herberticus@gmail.com>
Date: Tue, 7 Mar 2023 21:37:23 +0000
Subject: [PATCH] Large batch of improvements:

* The JavaScript RingBuffer structure updated correctly.
* Replaced the funnel graph with text - easier to read.
* Discovered that the current "parking_lot" could become unstable
  under very heavy load, and only with "fat" LTO. Since it's
  no longer recommended (recent change), removed it.
* Replaced the "lazy_static" macro suite with the newly recommended
  "once_cell" system. Less code.
* Full source format.
* Update some dependency versions.
