* update `test` and `dev` dependencies to `rio-tiler>=3.0.0a0`

* no changes since 3.0.0a0

* raise warning when using incompatible options for GDAL COG driver (https://github.com/cogeotiff/rio-cogeo/pull/212)

* update `click` version requirement to `>=7.0` to make sure `click.Choice` supports the `case_sensitive` option.

* allow external configuration (GDAL Env) for `cog_validate` (https://github.com/cogeotiff/rio-cogeo/pull/206)

python
from rio_cogeo import cog_validate

assert cog_validate("cog.tif", congig={"GDAL_DISABLE_READDIR_ON_OPEN": "EMPTY_DIR"})[0]


In previous version we were forcing `GDAL_DISABLE_READDIR_ON_OPEN=FALSE` in `cog_validate` function to check for external overviews.

Starting with version 2.3, it's up to the user to set the wanted GDAL configuration (e.g `EMPTY_DIR`: no external file check, `FALSE`: check for external files)
