Added voltage download submission option. Fixes #12

[gsleap]

Hi folks,

My first PR for Giant Squid! This allows the submission of voltage jobs. NOTE the server will reject a request if you are not in the mwavcs or mwaops MWA ASVO pawsey group.

Cheers

Greg

I'm not really looking at giant-squid any more, but your PR looks good 👍 I trust you've tested this and it works to your sanctification. Maybe Dev would like to cast their eyes over the code, but I reckon you can merge and release as you please.
