BUG/STY: fix GOLD updates

[jklenzing]

Description

Several bugfixes were pushed to develop for GOLD data while #161 was under review. Additionally, some data products were changed to use the cdasws functions for download. 2 of the 3 new products in #161 could use this, but the third was not in the cdasws database.

Updates #161 with latest bugfixes, style. Note that full functionality requires pysat 3.1.0. Basic functionality (loading single days, not multiple days) is maintained for earlier pysat versions, but will likely be re-addressed after pysat 3.1.0 is released.
