create a mesh grid from major and minor values.

given two arrays major_values and minor_values, this function generates a pair of 2D arrays representing the major-grid and minor-grid. the major-grid contains rows of major_values, and the minor-grid contains columns of minor_values.

import { assertEquals } from "jsr:@std/assert"

const
	y_values = [1, 2, 3],
	x_values = [4, 5],
	[yy_grid, xx_grid] = meshGrid(y_values, x_values)
assertEquals(yy_grid, [
	[1, 1],
	[2, 2],
	[3, 3],
])
assertEquals(xx_grid, [
	[4, 5],
	[4, 5],
	[4, 5],
