Add the 'feederassign' command to add/remove pets from feeders

[badnetmask]

I was looking to figure out a way to automate adding/removing a pet from a feeder, when I stumbled upon this project. I realized this feature didn't exist, so I took some time to write it.

Example usage:

surepy feederassign -d 123456 -m list
surepy feederassign -d 123456 -m add -p 654321
surepy feederassign -d 123456 -m remove -p 654321

There are a few caveats though:

• This has not been thoroughly tested to account for all possible errors.
• I made various assumptions about coding and output style based on reading other pieces of the code.
• The HTTP DELETE operation does not return data, so I had to add a weird fake return to the "call" function. I'm sure this can be improved.

I hope you find this useful.

Please, let me know what improvements you would like to see before merging.

Thank you.
