I'm trying to get a list of usernames in a large group (117 people), but populate_users only returns 100 items. The function doesn't take an upper bound page size, so it sticks with 100

#Get list of Tableau_Publishers
group_list = server.groups.get()
group_num = range(len(group_list[0]))
#Find Tableau_Publisher Group ID
for i in group_num:
    if group_list[0][i].name == 'Tableau_Publishers':
        publisher_id = group_list[0][i]
        print server.groups.populate_users(publisher_id)
        print len(group_list[0][i].users)

Populate_users appears to obey the default REST API request pagination, but doesn't accept a setting to bump the page size, and there is no documentation on the Groups endpoint at all.

Default should either be higher than 100, or accept input on max size.
