Options cannot be placed as 1st or 2nd argument

[Illu]

This should work:

$ pypy --no-space 5 🌴

But it currently returns an error "Size must be a number".

Right now, options must be placed after the size and emoji. It would be nice if they could be written anywhere in the command, like this:

$ pypy --no-space 3 👻 --no-copy

Maybe we have to use a command line parser to handle the arguments in a cleaner way.

This project is going too far :) anyway feel free to send me a PR, I'll be busy for a moment, no time for dev right now ..
