Add decimal place support

[almandsky]

As per #124

Here is the PR to add decimal place support. Default is 0, max decimal place is 3.

ms(60000, { decimal: 1 })                           // "1m"
ms(66000, { decimal: 1 })                           // "1.1m"
ms(-3 * 66000, { long: true, decimal: 1 })          // "-3.3 minutes"
ms(234234234, { decimal: 2  })                      // "2.71m"
ms(ms('10.5 hours'), { long: true, decimal: 1 })    // "10.5 hours"

@leerob @gmattie any chance for having this functionality added?

Is there literally any chance of this being implemented? I use it for years now, works flawlessly but it's a bit of hassle to always remember and look for the correct fork every time. It shouldn't even have any breaking features, only adding a one new (and quite useful one imho).
