squarewaveXYpolar(
    start: Point,
    direction_polar: number,
    amplitude: number,
    line_spacing: number,
    periods: number,
    extra_half_period?: boolean,
    extra_end_line?: boolean,
): Point[]
Generates an array of Points forming a 2D square wave pattern.
Parameters
- start: Point
  The starting point of the wave sequence.
- direction_polar: number
  The overall direction angle (radians) the wave travels along.
- amplitude: number
  The distance the wave peaks extend perpendicularly from the travel axis.
- line_spacing: number
  The linear travel distance between each perpendicular peak.
- periods: number
  The number of full wave cycles to generate.
- extra_half_period: boolean = false
  Set to true to add an extra half-cycle at the end.
- extra_end_line: boolean = false
  Set to true to emit a final travel segment matching the axis direction.
Returns Point[]
Array of Points traversing the square wave.
