[Feature proposal] Repeater settings generator

[matkam]

Why: The mesh will become large enough that region scoping will need to be configured on every repeater. Region scopes need to be coordinated.

Inspiration comes from:

• https://zindello.com.au/meshcore-regions-what-they-are-how-they-work-and-why-they-matter/
• https://regions.meshcore.nz
• https://gessaman.com/meshcore/regions/
• https://github.com/Andrew-a-g/meshcore-region-ideation

Proposal:

• Add a section in the nodes page, only for repeaters called "recommended settings" that includes a list of Meshcore CLI commands an admin can copy/paste to configure their repeater.
• Recommended settings will include region scope configuration, as well as arbitrary agreed upon settings for a region such as hash prefix mode, advert interval, agc reset interval, etc.
• There is a base layer for region scoping, similar to https://regions.meshcore.nz, of country code, state, county, and city/town.
• Additional regions and arbitrary settings would exist in a public GitHub repository. The format would be a set of JSON or YAML files that can be organized arbitrarily in directories. The files would include:
  • A friendly name for the region
  • Geo boundary, which would be a list of coordinates that enclose a region
• Regional representatives can submit PRs to manage their region's recommended settings
• Corescope would periodically read every file in the regional settings repository and use the data to populate the "recommended settings" section in the node page.

Future:
Connect to a client via USB/Bluetooth to be able to apply recommended settings to a repeater automatically. It would take the repeater's admin password, connect to the repeater, and apply the settings. There should be some retry mechanism per cli command sent to a repeater. And a mechanism to set and reset the path from the connected companion to the desired repeater.
