     * Expands the bits of the number `n` by inserting extra characters after each bit.

     * When `filler` is '0', it inserts k zeros after each bit (dilating the bits).
     * When `filler` is 'bit', it repeats the bit k times after the original bit (replicating the bit).
     *
     * @param n - The original number.
     * @param k - The number of extra characters to insert after each bit.
     * @param filler - Either '0' (to insert zeros) or 'bit' (to repeat the bit). Defaults to '0'.
     * @returns The new number after the expansion.
