docs: Parses a format string or object and returns format obj for use in rendering
  
  `format` is either a string with the default (positive) format, or object
  containing `pos` (required), `neg` and `zero` values (or a function returning
  either a string or object)
  
  Either string or format.pos must contain "%v" (value) to be valid
