Hyphens in TF operation names being written into generated C++ code

[PeteBlackerThe3rd]

using : utensor-cli, version 0.3.5

I've just found that if Tensorflow operation names contain hyphens these are translated directly into c++ identifiers in the generated code, resulting in invalid code.

I couldn't spot an obvious C identifier sanitiser function in the code, but hopefully this will be an easy fix.
