Bounds-check before reading length field

ReadTableLengthFromTable also assumes the raw slice is AddressBytesLength + 8 bytes long. A bad slice will panic here:

length, err := DeserializeUint64(bz[cursor : cursor+8])

Add the same defensive guard:

 func ReadTableLengthFromTable(bz []byte) (math.Int, error) {
     cursor := 0

     // read table handle address
     cursor += AddressBytesLength
