keyword arguments of to_raster are not propagated to rasterio

[philippkraft]

The call signature of pysheds.io.to_raster includes a **kwargs argument, which is unused.

It could easily be used to extent the rasterio profile with additional arguments, eg. compress. It is currently rather cumbersome to save a raster with a compression. @mdbartos, your code is so fast, I have mainly I/O as a bottlenck and compression would be super helpful (I have a workaround). I can create a pull request if wanted, but it would just extend the code creating profile_updates with the kwargs:

  profile_updates = {
        'crs' : data.crs.srs,
        'transform' : data.affine,
        'dtype' : data.dtype.name,
        'nodata' : data.nodata,
        'height' : height,
        'width' : width
    } | kwargs

Hi @philippkraft, sounds useful. I haven't worked with rasterio in a while, so I am not totally sure I understand the proposed change, but go ahead and create a PR with a proof of concept.

The idea is just the same, as in to_ascii. Additional keyword arguments are passed on to rasterio.open (instead to numpy.savetxt as in to_ascii). However, while implementing this, I've seen that the pgrid.to_raster code is duplicating the io.to_raster' code, whilesgrid.to_rastercallsio.to_raster. Shouldpgrid.py` changed in the same way?
