Workaround to make mac.get() fetch Interfaces

set the path to lowercase, calling:

system/vlans/1/macs/dynamic,00%3Aaa%3Abb%3Acc%3A00%3A11 works while system/vlans/1/macs/dynamic,00%3AAA%3ABB%3ACC%3ADD%3AEE does not.

payload change:

setting either depth or selector to None was enough to get it working. Having either set to None resulted in the GET call being without depth and selector in the URI.

DEBUG:urllib3.connectionpool:https://cx6100.example.org:443 "GET /rest/v10.08/system/vlans/1/macs/dynamic,00%3Aaa%3Abb%3Acc%3A00%3A11 HTTP/1.1" 200 362

I am new to this code so unable to right now judge how bad this impacts other calls.

https://github.com/aruba/pyaoscx/blob/master/RELEASE-NOTES.md#notable-changes-2 has a bit about MAC module being supported after the recent architecture changes in pyaoscx.

I have ran a pip3 uninstall pyaoscx and then python setup.py install to install this branch.
