Titiler

* relax version for rio-tiler and cogeo-mosaic

python
"rio-cogeo~=2.0"
"rio-tiler>=2.0.0rc1,<2.1"
"cogeo-mosaic>=3.0.0a17,<3.1"

* split `tile()` for `MosaicTilerFactory` method (https://github.com/developmentseed/titiler/issues/147)

* update for rio-tiler==2.0.0rc1, cogeo-mosaic==3.0.0a17 and morecantile==2.0
* split `tile()` factory method (https://github.com/developmentseed/titiler/issues/141, author fredliporace)

* avoid changing mutable TMS and Colormap list by using deepcopy.
* quiet/turn off logs
* add logger middleware (https://github.com/developmentseed/titiler/pull/139)

* update for rio-tiler 2.0.0b17, which now support TMS (morecantile) by default.
* update fastapi minimum version to 0.61

**breaking changes**

* removed TMSTilerFactory (because default reader built with rio_tiler BaseReader should support TMS).

Note: We changed the versioning scheme to `{major}.{minor}.{path}{pre}{prenum}`

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