[FEATURE] Optimisation of detection of size of text in nodes in AST with a binary search.

[fullwoodenshovel]

This block of code (responsible for detecting what the maximum size of text that would be smaller than spacing / 1.7) could be optimised by using a binary search instead of a linear search:

matrix-visualiser/src/main.rs

Lines 382 to 389 in 94ee3b9

	while
	let TextDimensions { width: test_width, offset_y: test_y, .. } = measure_text(text, None, scale, 1.0) &&
	test_width > spacing / 1.7
	{
	scale -= 1; // could be optimised with binary search instead
	text_width = test_width;
	offset_y = test_y;
	};
