Can't access audit-log functionality.

[EpicnessTwo]

As the audit log functions within Restcord are under the class of audit-log, trying to access them returns the following error.

PHP Fatal error:  Uncaught Exception: No category with the name: audit in /path/to/code/vendor/restcord/restcord/src/DiscordClient.php:127

I was able to hotfix this in the local files by changing 2 of the references in service_description-v6.json from audit-log to auditlog. Not too sure if this is the best fix for this but it works in the examples that I'm attempting to use.

I have fixed this in #174, if that gets merged you would access it as follows:

$client->auditLog
