v0.2.6

Bug fixes:

• #11 pixel_overlaps no longer changes the gdf_in outside of the function

Functionality tweaks

• added agg.to_geodataframe(), similar to agg.to_dataframe(), but keeping the geometries from the original shapefile
• adapted xarray's ds.to_dataframe() in agg.to_dataframe(), which has better functionality
• .csvs now export long instead of wide, using the output from ds.to_dataframe() above
