can you add Limbo verifier?

Based on the sites example, they seem to truncate after 2 decimals, no rounding. I had to multiply by 100000000 then divide.

Had to use a custom toFixedTrunc func to truncate value.

case 'Limbo':
        //100000000 / (81089656 + 1) * (1 - 0.01) = 1.220870868895154
        const bytes = Math.floor(this.bytes_to_number(this.bytes(8)) * 100000000);
        const result = (100000000 / (bytes + 1) * (1 - 0.01));
        return this.toFixedTrunc(result, 2);
