add colorize support for JSON

[fredless]

Problem to Solve

no in-built function to colorize JSON

New Feature/Solution

Function that provides rich colorize functionality for JSON snippets - distinguishing between strings, numbers, objects, array, booleans, nulls, etc.

Alternative Solutions

Javascript colorize works but doesn't distinguish between many of the elements above.

Additional Context

There is a certain appreciable irony that OneMore configs are driven with JSON files 😇
