Updated the AES-GCM encrypt function to avoid one heap memory allocation. The internal GCM implementation uses 'sliceForAppend' that will allocate new memory if the 'dst' buffer does not have enough capacity. With this fix, the slice 'nonce' has now enough capacity to be used as 'dst' without memory re-allocation.
