[c-lightning] LNLink: a new iOS wallet for clightning

[William Casarin]

Hey Team,

I've just released the initial TestFlight for a new clightning iOS
wallet I've been working on.

This app provides a simple and fast way to pay for things directly from
your node without running Spark, VPN or Tor tunnels. It knows how to
speak the lightning protocol, and connects directly to your lightning
node over the lightning network port. It uses a plugin called commando
for executing RPC calls to your node!

Benefits of this:

- It's extremely fast/low latency unlike Tor hidden service tunnels.
   Lightning network has less round-trips than https/TLS which
   contributes to the speed as well.

- It's secure. The lightning network is already very secure, and the
   lnlink connection uses runes that can be time restricted, restricted
   to specific calls, restricted to read-only, etc.

- Don't need to run any VPN or Tor

- Don't have to worry about UDP port blocking with Wireguard + Spark

- Don't need to run additional sidecar software like Spark

- You can set your lightning network port to 443 to make the lnlink
   connection effectively unblockable.

This is the very first alpha release, so it's a bit slim on the feature set.

Planned features:

- bolt12 support (subscriptions and more eventually!?)
- lnurl
- receiving sats
- paying custom amounts
- listing previous payments
- liquidity ads ??
- accounting ??
- tor support? (ugh but fine)

Check it out and join the TestFlight beta! I need clightning testers!
