Request: Support for .ino files (Arduino sketches)

[elektronikworkshop]

Hi Zak,

thanks for this great tool - one I was looking for for a long time.

I'm currently documenting some Arduino libraries and I use your tool to embed the example code into the readme. It works perfectly but spits out a warning of course:

  Writing README.md with embedded changes.

The embedme-code was

```cpp
// examples/lcdpong-butenc/lcdpong-butenc.ino#L20-L59
```

The .ino are Arduino sketches and are plain C++, perhaps this could be implemented as an alias or so?

I just created a pull request for this which will close this issue automagically when merged.
