Example to test functionality

Hi, are there any examples available to test functionality of the crate? There doesn't seem to be much about that in the documentation.

Also, when using boringtun cli, I'm unable to assign IP Addresses to my interfaces. Using the command
`wg setconf `
It gives this error:
`Line unrecognized: `Address=10.100.100.10/32'
Configuration parsing error`

So im unable to assign an address to it too, although if I setup an interface using wg-quick instead I am able to assign an address and ping it too.
