Develop (#135)
* Allow symfony 5 (#106)
* Added premium_since to GuildMember model (#116)
Note that I was unable to utilise the
downloadServiceDefinition binary, as it is dependent
upon a web resource that no longer appears to exist
(https://discord-service-definition.herokuapp.com/)
Accordingly, GuildMember.php had to be edited manually,
along with the service definition file.
