fix(emoji): for installable python apps in develompment

* When it comes ro tunning such module in development, Python
can be executed with the `-m` option, because need them like
this when app is installed.
* Now run like this but you must be in the `src` folder.

```shell
python3 -m mdsanima_dev.emoji
```

So this is a simple but important to run without
`ModuleNotFoundError: No module named mdsanima_dev`.
