/**
* Represent a duration in seconds as a string
*
* Input should be a finite number; output will include one or two `:`
* separators, and match the pattern `hhhh:mm:ss`, possibly with a leading `-`
* for negative values and a trailing `.sss` part for non-integer input
*
* @memberof Formatters
* @param {number|string} value - A finite number, or its string representation
*
* @example
* var mf = new MessageFormat();
*
* mf.compile('It has been {D, duration}')({ D: 123 })
* // 'It has been 2:03'
*
* mf.compile('Countdown: {D, duration}')({ D: -151200.42 })
* // 'Countdown: -42:00:00.420'
