Does not fetch all mullvad servers

The GL.iNet interface does not fetch all the Mullvad servers.

I generally use the servers in New York, but just this morning Mullvad removed all the New York servers that were named with numbers in the 100s and 200s (e.g. us_101) and replaced them with 300s-600s. Refreshing servers in the interface or re-creating the Mullvad setup did not fetch these new servers—it only fetched USA servers in Miami and Chicago.

I was able to get them by importing a config zip from Mullvad.
