Feature request: output parsed statements in tree form to show execution order

[commanderguy3001]

sometimes, especially for debugging large commands, I would love the option to output the parsed statement im the form of an AST or dimilar, assuming that's how the numbat engine works internally.

I have no specific idea of how the interface for this should look like, but probably adding an internal function that just outputs the tree view of the last executed statement (that isn't just a type casting) would be the way to go.

This is basically what the pretty-printing already does, except that it does remove (some) unnecessary parentheses:

numbat/numbat-cli/src/main.rs

Lines 503 to 509 in e188be6

	if pretty_print {
	for statement in &statements {
	let repr = ansi_format(&statement.pretty_print(), true);
	println!("{repr}");
	println!();
	}
	}

we could probably add another pretty-printing mode that skips removing parentheses.

What kind of precedence rules do you typically have problems with?
