Introducing `Module::load_from_bytes()`

[vmx]

It's currently possible to directly embed a CUDA module via Module::load_from_string(). It is using a CStr, which is meant for a list on nul-terminated bytes (strings) and not for binary data.

Hence I propose introducing Module::load_from_bytes(), which does the same thing, the only difference will be that the input will be a byte slice &[u8]. You can then use the include_bytes! macro to include the module.

I would even remove the Module::load_from_string() and only have Module:load_from_bytes(), but I'd leave this decision to the maintainers.

I'm happy to do a PR, if that's a feature that would be accepted.

I forgot to mention that the inlcude_str! macro has additional restrictions, the input needs to be valid UTF-8, which leads to problems as described in issue #47.

The implementation could look like this: vmx@2c39a40
