Function max_7219_led_matrix_util::transpose_single_display_data

pub fn transpose_single_display_data(
    data: SingleDisplayData
) -> SingleDisplayData

This does a transpose operation on the SingleDisplayData-Matrix and is a helper function for remove_gaps_in_display_text. Cols become rows and rows become cols. Example:

let _ = [
    0b10000000,
    0b10000000,
    0b10000000,
    0b10000000,
    0b10000000,
    0b10000000,
    0b10000000,
    0b10000000,
    0b10000000,
];

becomes

let _ = [
0b11111111,
0,
0,
0,
0,
0,
0,
0,
];
