Netmask vulnerability

This library uses the "pac-resolver" package which currently has an open PR to upgrade netmask to 2.0.1

TooTallNate/node-pac-resolver#25

Once this is closed and a new version released, this project will also need to update.

@yinzara TooTallNate/node-pac-resolver#25 was merged yesterday. It seems that this project won't need the update, since pac-resolver released a new patch version. It should get picked up automatically by pac-proxy-agent.

@juan-restrepo Is correct, the semver range allows for the new 4.1.1 to be picked up. Please run yarn upgrade or equivalent.
