I've spent hours on trying to expose createEmbeddedLayer but
had no luck and now giving up (no more fun for me).

When I uncommented the createEmbeddedLayer method in the
qgsproject.sip file, the sip compiler complained with:

 unsupported function argument type - provide %MethodCode and a valid C++ signature

Since I didn't so many %MethodCode used I tried (unsuccessfully)
to provide a %MappedType in conversions.hpp instead.

If anyone has further pointers I might get back on the issue.
