New feature I could implement: --output json in order to agregate data from multiple repositories

Hey @oleander Nice to see you have some time to dedicate to your open source projet :)

Following the closing #73 I'd like to implement a related feature in order to agregate data from multiple repositories

git fame --output json

would output something like:

{
  [
  "name": "Foo",
  "email": "test@example.com"
  ]
}

So https://stedolan.github.io/jq/ can be used to extract and combine the result of multiple repos

Sure, go for it!
