May you add support to Cloudflared please?

Hello there,

Some of my destination servers are not directly accessible.
I have configured them to be accessed via Cloudflare Tunnel (Cloudflared, WireGuard UDP VPN)

It just works like traditional SSH, but with this binary installed:
https://github.com/cloudflare/cloudflared/releases/

Traditional SSH config:
```
Host myhost.com
User ubuntu
IdentityFile ~/.ssh/myhost.key
```

SSH config with Cloudflared
```
Host myhost.com
User ubuntu
IdentityFile ~/.ssh/myhost.key
ProxyCommand /usr/local/bin/cloudflared access ssh --hostname %h
```

Could you add support for this one please?
Thank you very much.

Review the drone-ssh repository's SSH configuration and command-handling entry points, then compare them with the provided Cloudflared ProxyCommand example. Support should allow the shown Cloudflared configuration to establish the SSH connection and preserve the existing user and identity settings.
