[Feature Request] WNBA players & teams in static data

[cosmicac]

First of all, thank you to all of y'all who maintain this package! I've been playing around with it and it's awesome.

I noticed that the WNBA players and teams are not in the static data file. I'm working on something that requires this data.

How is the data in this file generated? Is there a script somewhere in this repository that generates this? I'm happy to open a pull request to add the WNBA players and and teams, but wanted to check to see if there's a standard way the static data is generated.

Thanks!
