Using the status module across large workspaces

[0o-de-lally]

I've been using abscissa in several apps in a large workspace with other non-abscissa apps. I'd like to use the status.rs in those other apps, or in common libraries. This means instantiating Streams before using status_info! directly in the non-abscissa module.

However that means abscissa apps will fail with "terminal streams already initialized!". Would be nice if status didn't have a panic when the terminal is already initialized, or perhaps reusing.

abscissa/core/src/terminal.rs

Lines 17 to 22 in 6630727

	/// Initialize the terminal subsystem, registering the [`Streams`] static
	pub(crate) fn init(color_choice: ColorChoice) {
	STREAMS
	.set(Streams::new(color_choice))
	.unwrap_or_else(|_| panic!("terminal streams already initialized!"));
	}
