Add compression on raster save

[AdrienWehrle]

There is currently no compression specified for the creation of the different rasters. Let's add an option for compression.

Mainly happening here through output_meta:

earthspy/earthspy/earthspy.py

Lines 1065 to 1067 in 9ee52fb

	# write mosaic
	with rasterio.open(date_output_filename, "w", **output_meta) as dst:
	dst.write(mosaic)

Where should I put the compression option ?

[AdrienWehrle]

I think best would be to have it in set_query_parameters and set to no compression by default. Then user can pass various compressions that correspond to rasterio compression options.

You can see how to compress on save with rasterio eg here. Then I think passing the compress argument in the output_metadata update here should work.

A get_raster_compression method could be added here where we'd make sure only compression keywords matching rasterio's are passed. Otherwise raise an Error.
