ZSTD missing codec
Thanks for this lib/plugin, it's really helpful and avoids having to guess which creation options are good for remote access.

I'm encountering a problem with the `zstd` `cog-profile`.

When running:
```
rio cogeo create -p zstd S2A_MSIL1C_20190112T175711_N0207_R141_T13UFQ_20190112T194934__B01.jp2 out.tiff
```

I get the following traceback:
```

```

I run this in a fresh virtual environment where I have `pip install rio-cogeo`.
Is the problem that the `GDAL` lib that came packaged with the `rasterio` wheel doesn't support `ZSTD`? That seems surprising. For reference, the `rasterio` wheel that was installed is https://files.pythonhosted.org/packages/e1/2e/af9bfa901b890800b25428ab9846fe4e91818a94ede227c1a2d4410bac54/rasterio-1.0.28-cp36-cp36m-manylinux1_x86_64.whl

Or is something wrong with my local setup?
