Compute the sizeof using this.

var maxHandshakeSize = unsafe.Sizeof(BlockAnnounceHandshake{})

Also, you can store it in a constant, since size wouldn't be changing.
Add a test for it as well. The size will be 72 due to the padding of the first byte.

func TestSizeOf(t *testing.T) {
	require.Equal(t, maxHandshakeSize, uint32(72))
}
