Rio-cogeo

* switch to `morecantile` and update the web-optimized creation method to better match GDAL 3.2.
* add `zoom_level_strategy` options to match GDAL 3.2 COG driver.
* add `aligned_levels` (cli and api) to select the level of overview to align with the TMS grid.

**Breaking Changes:**
* removed `--latitude-adjustment/--global-maxzoom` option in the CLI
* removed `latitude_adjustment` option in `rio_cogeo.cogeo.cog_translate`
* updated **overview blocksize** to match the blocksize of the high resolution data (instead of default to 128)
* for web-optimized COG, the highest overview level will be aligned with the TMS grid.

* remove `pkg_resources` (https://github.com/pypa/setuptools/issues/510)

* Update max IFD offset to 300 bytes (https://github.com/cogeotiff/rio-cogeo/issues/158)

* Make sure Alpha band isn't considered as an internal mask by `utils.has_mask_band` (156)

* Fix wrong min-zoom calculation in `rio_cogeo.cogeo.cog_info`
