Quotation marks aren't being detected properly within the iotile cmdline on Windows

On Windows (The LabPC), using PowerShell, and tried to force a proxy when connecting to the controller of my Access Point. Here's the command and error:

(venv) PS C:\Users\LabUser\tfroehlich> iotile hw --port=bled112
(HardwareManager) connect 0x12d2
(HardwareManager) get 8 --force='NRF52 '
Traceback (most recent call last):

(HardwareManager)

The same command sequence worked fine on my Linux PC :

$ iotile hw 
(HardwareManager) connect 42
(HardwareManager) get 8 --force='NRF52 '
(NRF52832Controller)

The windows test was with Python 3.7 and I got the same results with the Python test with both Python 3.7 and 3.5.

The workaround is to get the proxy from an initial command line invocation, which works properly.
iotile hw --port=bled112 connect 0x12d2 get 8 --force='NRF52 '

@timothyfroehlich Another workaround that should work is to quote the entire command line argument:

get 8 "--force=NRF52 "
