Decode a string representation of 128 bit value (26 characters) as a pair of (Long, Long) (128 bits)
Decode a string representation of 128 bit value (26 characters) as a pair of (Long, Long) (128 bits)
Note that technically 26 characters x 5 bite can represent 130-bit values. This method will discard the top 2 bits
from the string as ULID only uses 128 bits.
