Utility script to help diff/log Perspective view.json files under git.

The git "textconv" feature is intended to convert binary files to a
rough text approximation, so that viewing diffs or logs of those files
will provide an idea of what changed.  This script can be used as a
textconv on Ignition Perspective view.json files to extract JSON-encoded
script blocks into something that almost resembles proper Python

RegEdit tweaks circa Win10 22H2:

- Set RTC to UTC (if dual-booting Linux)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation
DWORD RealTimeIsUniversal = 1
(may act flaky if you don't disable auto-timezone and auto-sync first, although it sometimes seems 
okay to turn them back on after rebooting with this setting in place?)

- Disable Cortana
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windows Search

This is ultra-low-priority junk I had stuck in my head last night, and I figured writing it all down might be the best way to stop thinking about it.

One of the issues with Sparkplug B is support for systems with multiple application nodes. Specifically, in terms of coordinating BIRTH messages.

These thoughts are not compatible with Sparkplug B, but are still interesting, possibly for a future generation... I'm trying to think them through before badgering people on the committee with them.

I'm contemplating what happens if you split the variable and non-variable portions of the NBIRTH into two messages, publishing the non-variant portion persistently, and using the LWT to both announce the node has gone offline and clear the persistent publish.

Let's call the new persistent topic NSCHEMA.
