ssm-diff errors when pulling a numerical only value from parameter store

[connerstobie]

In parameter store if you have a numerical only value for a parameter and you ssm-diff init that parameter the following error occurs.

'int' object has no attribute 'splitlines'

key: /some/key value: 123456

It will work if it is wrapped in quotes in parameter store or changed from a non numerical only value but that limits the values we can use if we want to us this tool.
