I'd like to know if it's possible to read/write GML files (or even KML files) using Fiona.

Fiona documents don't specify what drivers we can use. I read some answers about the drivers that are avalaible but I still haven't figured out the right answer.

These two different sentences print a different number of drivers. The first one doesn't include GML o KML (in fact there are very few formats supported). 

```
print(fiona.supported_drivers)

```

vs

```
print('\n'.join(sorted(fiona.drivers().drivers())))

```

I know how to do it using GDAL/OGR but I want to do the same using Fiona if it's possible.
