Closing in on 0.6.0

[andrewdavidmackenzie]

I've been busy these past few weeks, with a lot of improvements and new features already done, and I'm burning thru the list of issue for 0.6.0 release.

• storing of config set from GUI in file or flash on device, so functioning continues after a power cycle. Allows setting things up, unplugging device and putting in definitive place
• GUI loads config from device on connect, so UI always reflects the active HW setup.
• USB discovery of pi pico devices. Show hardware details, and connect to it.
• For pico W devices you can also configure/reset the Wifi via USB. This is stored in flash to override the built-in wifi config if you want.
• mDNS discovery of Pis on the network, show device details, connect via TCP or Iroh.
• mDNS discovery of Pi Pico W on the network, then connect via TCP...
• UI improvements and bug fixes...
• and others I can't recall but will include in the release notes

I was kind of holding out for the full USB implementation for Pi Pico (not W) before releasing....but feedback welcome on that...

Thoughts welcome, and Input on 0.7.0 list appreciated!!
