* [warp_add_rpcs] initial update to reproject to support rpcs
* catch kwargs in _calculate_default_transform
* fix allocation of crs to wrong dataset (was src, now dst) in _calculate_default_transform. Specifically where we went from GDALCreateGenImgProjTransformer -> GDALCreateGenImgProjTransformer2
* pass kwargs to calculate_default_transform (to be passed to transformer
* update docstrings
* update documentation
* add debug messages for kwargs used to set Transformer options
* Don't capitalize RPC_DEM transformer option value, as it might be a path
* includes existing changes from https://github.com/mapbox/rasterio/pull/2030, better support for computation of calculate_default_transform with just gcps or rpcs
* adds testse
* Remove an empty line
Mainly to trigger a new build on travis-ci.com
* add new test file (Largely derived from RGB.byte.tif)
* Fix incorrectly encoding RPC metadata as transform options
Was checking for transformer option RPC_DEM in the RPC metadata by mistake
