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

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.

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
