Add reversed usage zm

[JoschuaSchneider]

The current mz implementation allows creating a formatter function bound to a number like this:

const formatter = mz(5)
formatter`number is {singular|plural}`
formatter`value of number is $value`

This is useful when you have one number that you need to use for multiple formatted strings. But you might also need one set string formatted to different numbers like this (I propose the name zm for this):

const template = zm`number is {singular|plural}`
template(5)
template(0)
