Pass io to zeit.instant only when needed

[der-teufel-programming]

No source other than now requires it

Is there a pattern emerging here? I feel like passing it in on the config is not how this would be done with an allocator. What do you think about making it a nullable param?

fn instant(maybe_io: ?Io, ...)

I think it might be nicer to have two functions, one with a config, and one without but it takes an Io.

fn instant(config: Config)
fn instantNow(io: std.Io, tz: TimeZone)

The new instant function can internally pass an undefined io to the current implementation of instant.

I agree that separating creating now from creating an instant from another, constant, source could benefit the API
