    …ecisionBits

As found by OSS-Fuzz, large numbers may overflow the current maxDecBitLen because
it assumes that DecimalPrecisionBits (60) can always be represented by Precision (18)
base-10 digits. Since 2^60 is larger than 2^18, this assumption is false.

This change fixes cosmos#11732 by only allowing 59 bits of precision on top of the 256
maxBitLen allowed for the integer part.
