Set sets offset + size to value

(offset, size uint64, value []byte)

// Set sets offset + size to value
func (m *Memory) Set(offset, size uint64, value []byte) {
	// It's possible the offset is greater than 0 and size equals 0. This is because
	// the calcMemSize (common.go) could potentially return 0 when size is zero (NO-OP)
	if size > 0 {
		// length of store may never be less than offset + size.
		// The store should be resized PRIOR to setting the memory
		if offset+size > uint64(len(m.store)) {
			panic("invalid memory: store empty")
		}
		copy(m.store[offset:offset+size], value)
	}
}

// Set32 sets the 32 bytes starting at offset to the value of val, left-padded with zeroes to
// 32 bytes.
