What version of bat are you using?
bat 0.15.4

Describe the bug you encountered:
Bat does not seem to highlight JSON files very well. Specifically, there's almost no highlighting at all, even though the screenshots would indicate it knows how to highlight keys differently to values in maps.

Describe what you expected to happen?
Something that looks more like the picture on #48
