[DataUtils] Addition of Nickname Column to rolemembers command

[Coding-Sock]

Is your feature request related to a problem? Please describe.
When using rolemembers to pull a list of all members for a server, some users are more easily identified by their given nickname rather than their actual username.

Describe the solution you'd like
It would be nice if the rolemembers command could also return a column with the related nickname at the time of the query such that results would be:
ID, Name, Nickname

Describe alternatives you've considered

Additional context
Part of this desire is to help manage a server where everyone is required to set a nickname (which doesn't change after). Adding this additional column (either optionally or always included) would be very useful for scenarios like this where the name you see differs from the username and getting a list to cross reference that includes it all is most useful.
