Parse int larger than u8

Ah, gotcha!

Thanks for the clarification. That's just me being a newb in zig... More docs are always welcome though 😄 Thanks for the useful library!

The second argument to clap.parsers.int is the radix aka, the base in which we parse the number. For 10, this means that "10" => 10. For 2 this means "10" => 2. I don't think the standard library parseInt supports base 1024.

I could rename it from radix to base to make this more clear. I think the standard library used to call it radix, but changed to base at some point after I wrote that function. Consistency is hard :)

This seems to be a misunderstanding of what the second argument of clap.parsers.int does. I've added some documentation to the function in this PR. Hopefully that should avoid future confusion
