Hi,
I tried adding [Audiobookshelf](https://www.audiobookshelf.org/) as a
new service to SHB.
Not sure whether you want this service in SHB at all, but thought I'd
create a PR just in case.
The service runs, but seemingly fails to add an entry to the nginx
config, so it is not reachable. I created the service by basically just
copying deluge and then adapting. Any idea why the nginx subdomain isn't
being created?
The config I used to add this to my SHB server is:
```nix
shb.audiobookshelf = {
enable = true;
domain = "sliper.xyz";
subdomain = "abs";
dataDir = "audiobookshelf"; #turns out this is actually the working dir of the service (/var/lib/<dataDir>)
authEndpoint = "https://auth.sliper.xyz";
};
// ... in shb.authelia.oidcClients
redirect_uris = [ "https://deluge.sliper.xyz" "https://abs.sliper.xyz" ];
```
ps. I also need to fix tabs->spaces. Forgot to set up nvim.
