Requires hightime>=0.2.0

[tmhofler]

Description of issue

Seems to require hightime >=0.2.0 but a minimum version is not specified.
Ran into this because I had hightime 0.1.0 installed before installing nidcpower==1.3.0

System report

python -c "import nidcpower; nidcpower.print_diagnostic_information()"

Traceback (most recent call last):
File "", line 1, in
File "C:\Users\nitest.virtualenvs\nidcpower_test-yBwmuPo5\lib\site-packages\nidcpower_init_.py", line 10, in
from nidcpower.session import Session # noqa: F401

def fetch_multiple(self, count, timeout=hightime.timedelta(seconds=1.0)):
AttributeError: module 'hightime' has no attribute 'timedelta'
```

Steps to reproduce issue

pip uninstall hightime
pip install hightime==0.1.0
pip install nidcpower==1.3.0
python -c "import nidcpower"
