Wireguard

What's Changed

* Simplified peer removal by jnhmcknight in https://github.com/fictivekin/wireguard/pull/16
* Peer Service Interface and Config Customizability by jnhmcknight in https://github.com/fictivekin/wireguard/pull/17

**NOTE:** This release contains a breaking change as all references to `.config()` need to be updated to be `.config` and any custom `Config` class needs to be either passed to the `Peer` or `Server` object at instantiation or will need to be set as `.config_cls = MyCustomConfigClass` at any later point in the `Peer` or `Server` objects' lifecycle.

**Full Changelog**: https://github.com/fictivekin/wireguard/compare/v0.4.0...v1.0.0

- Allows passing a list of peer dict info for the `peers` keyword during Peer/Server instantiation (10)
- Fixes a bug with passing a list of Pre/Post Up/Down directives, which was causing undesired nesting (12). Thanks UrfinJuice11 for identifying that problem.

What's Changed
* Allows setting the IP directly via the server subnet argument by jnhmcknight in https://github.com/fictivekin/wireguard/pull/5
* Built-in JSON exports by jnhmcknight in https://github.com/fictivekin/wireguard/pull/7

Previously, IPv4 and IPv6 weren't cleanly handled, and you could arrive at situations where one was overriding the other. This cleans that up, handling each separately, but allowing the instantiation to have them combined, as WireGuard itself has them combined within config files.
