Rio-tiler

* switch from `functools.lru_cache` to `cachetools.LRUCache` to allow unashable options in `rio_tiler.io.stac.fetch` function (https://github.com/cogeotiff/rio-tiler/pull/471)

* avoid useless call to `transform_bounds` if input/output CRS are equals (https://github.com/cogeotiff/rio-tiler/pull/466)
* make sure `geographic_bounds` don't return inf or nan values (https://github.com/cogeotiff/rio-tiler/pull/467)

* no change since `3.0.0a6`

* add `rio_tiler.utils.resize_array` to resize array to a given width/height (https://github.com/cogeotiff/rio-tiler/pull/463)
* use `resize_array` in `ImageData.create_from_list` to avoid trying merging array of different sizes (https://github.com/cogeotiff/rio-tiler/pull/463)

**breaking changes**

* update `MultiBaseReader` and `MultiBandReader` to be their own abstract classes instead of being subclass of `BaseReader`.
* put `reader` attribute outside of the `__init__` method for `MultiBaseReader` and `MultiBandReader`.

* allow the definition of `geographic_crs` used in the `geographic_bounds` property (https://github.com/cogeotiff/rio-tiler/pull/458)
* use `contextlib.ExitStack` to better manager opening/closing rasterio dataset (https://github.com/cogeotiff/rio-tiler/pull/459)
* moves `BBox, ColorTuple, Indexes, NoData, NumType` type definitions in `rio_tiler.types` (https://github.com/cogeotiff/rio-tiler/pull/460)
* better types definition for ColorMap objects (https://github.com/cogeotiff/rio-tiler/pull/460)
* fix some types issues (https://github.com/cogeotiff/rio-tiler/pull/460)

* refactor `SpatialMixin.tile_exists` to compare the bounds in the dataset's coordinate system to avoid coordinates overflow (a TMS CRS bounds can be smaller than the dataset CRS bounds) (https://github.com/cogeotiff/rio-tiler/pull/455)
