How to adjust result limit on band.getDiscography

[MGPAlpha]

I'm attempting to use this project to get data on a particular band, and using getDiscography() consistently only returns the first 16 results. The band I'm trying to get data for has over 50 releases, so that presents a problem for me. I have also tried it with other bands, and it still only returns a maximum of 16 results. Is there a way to increase the number of albums it will return, or to request additional pages of those results? I couldn't find anything in the docs about this.
