static fun decodeULong(source: Bytes, bitLength: Int): Long (source)
Read a SSZ encoded unsigned long integer from a Bytes value.
source - the SSZ encoded bytes
bitLength - the bit length of the integers to read (a multiple of 8)
InvalidSSZTypeException - if there are insufficient encoded bytes for the desired bit length, or the decoded value was too large to fit into a long
EndOfSSZException - if there are no more SSZ values to read
Return
an unsigned long
