number_to_human helper method

[jwoertink]

In rails, I have this method

format = number_only ? "%n%u" : "%n%u #{thing.pluralize(number)}"

    number_to_human(
      number,
      format: format,
      precision: 2,
      units: {
        thousand: 'k',
        million: 'm'
      }
    )

Which allows me to output something like "1.5k Users". The closest we have right now is something like:

text count.humanize
text pluralize(count, "User")

which would output "1.5k 1500 Users". It would be nice to have this helper method added in.

After a little thought, the humanize method built in to crystal already does most of this. We can also just use wordsmith to pluralize the word without the count... So really this may not even be needed. Maybe just some examples floating around 🤔
