REQ: Add ability to generate and export a WG config for a (different) node

[xxxserxxx]

I'd like to be able to add mobile devices (phones, tablets) to a Wesher-configured network. I assume that, since wesher sets up WireGuard networks, that this would be possible using the (e.g.) Android Wireguard app with the right config.

I'm imagining something like this:

1. On a desktop node: `wesher --cluster-key XXXXX --join x.x.x.x --export > mobile.txt`
2. Copy `mobile.txt` to mobile device
3. Import `mobile.txt` in Wireguard app
4. Enable interface

Wesher does some hostfile magic, among other things, and this would obviously be missing on the mobile device, but this would be a start to making it easier for mobile apps to join a Wesher network.

Any interest from the devs on this?

Mobile support would be awesome.

@bbigras naggie/dsnet is very similar to this project (it's also Go); it does this (dumping out a config) by default.

hey @xxxserxxx!
It would be indeed cool to have this possibility, but unfortunately adding "proper" mobile support requires significant work, which I'm unlikely to be able to invest in the forseeable future.

The dump/import workaround might be doable, though. I'm just unsure if it's worth it: the whole idea of wesher is keeping mesh membership up-to-date. This workaround would provide you only a "snapshot" of the mesh, which could drift pretty fast.
