This allows the use of gems like https://github.com/chanzuckerberg/ruby-prof-speedscope : - change `--printer` can take a class name instead of just a name of a builtin - add `--printer-require` for a require for a printer - add `load_printer` which is called during parse_args... after they are parsed, but before checking the output directory I initially tried not adding --printer-require, and re-using --require-noprof, but that didn't load the printer in time.
