This change adds support (almost all of) the same mixed Complex-Real operations that nim's complex module support. This also changes a bit some of the existing mixed ops. In particular, we used to support mixed ops of Complex64 with _any_ kind of number (including integers) but they did not support Complex32 - float32 ops. While being able to mix Complex64 with ints (for example) was nice, it was not consistent with nim's own complex library and also it would have required adding many more operator overloads, so I decided to just be consistent at the cost of a little usability in a small number of cases.

Note: This is a DRAFT because I'd like to reduce the number of functions that are needed. At the moment I had to create a lot of versions of each operator, to support all combinations of (Tensor-Tensor / Tensor-Scalar / Scalar-Tensor) x (Real-Real / Real-Complex / Complex-Real).
