We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Set python package version explicitly and expose in package
The cog python package sets version metadata but this has never been updated:

```python
In [1]: from importlib.metadata import version

In [2]: version('cog')
Out[2]: '0.0.1'
```

In addition, there's no `__version__` property on the package. This isn't essential but it would be nice to have this too:

```python
In [3]: import cog

In [4]: cog.__version__
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In [4], line 1
----> 1 cog.__version__

AttributeError: module 'cog' has no attribute '__version__'
```

It would be really nice to do this in a way that:

- returns the same version from both of the above
- returns the tagged version in tagged builds (e.g. `0.3.4`)
- appends git metadata when not on a tagged build (e.g. `0.3.4-dev+630e696`)
