add auth_client_id and auth_client_secret flag

Hello there,

I use a MASQUE tunnel my Cloudflare config. But would be good a other one (with different profile settings, like different split tunnel mode) based on wireguard. The only way , if i able to add add auth_client_id and auth_client_secret. it store it in /var/lib/cloudflare-warp/mdm.xml , the format is here:

```
auth_client_id
88bf3b6d86161464f6509f7219099e57.access
auth_client_secret
bdd31cbc4dec990953e39163fbbb194c93313ca9f0a6e420346af9d326b1d2a5
```

It possible that also need "organization" key.

You able to change your srcipt, that support these configuration?
