Integration tests can only be run with the password to the "icepyx_devteam" URS account

I work around this with this change:

diff --git a/icepyx/tests/conftest.py b/icepyx/tests/conftest.py
index 5bc5eb8..4c643f6 100644

     with open(netrc_file, "a+") as f:

But I'm not sure why this is the way it is, so I figured I'd start with an issue :)
