Allow custom args in hikari.internal.ux.print_banner

[zunda-arrow]

Summary

Allow any args dict to be used in hikari.internal.ux.print_banner

Why is this needed?

It is difficult to add extra information that changes to the banner. For example, a version number. Allowing custom args to be passed in would make this extremely easy,

Ideal implementation

I think the a kwarg should be added.

async def print_banner(package, allow_color, force_color, args=None):
    if args is None:
       # Set args to the current version

Updating args may also work

async def print_banner(package, allow_color, force_color, custom_args=None):
    args = {...}    
    if custom_args:
        args.update(custom_args)
