New Env class and tests. More logging, tests, safer environment Remove usage (deprecated) of rasterio.drivers() Also pep8 cleanups throughout the tests and a fix for unchecked dtypes when opening a dataset in 'w' mode. Now we can simply import warnings in __init__.py. In the deprecations tests, we needed to see a single warning only one time to avoid multiple drivers() warnings. Add a global env. Add rasterio.env.setenv()
