===========================================================
DeleteBasins(basins,pathout)
===========================================================
this function deletes all the basins in a basin raster created when delineating
a catchment and leave only the first basin which is the biggest basin in the raster
Inputs:
----------
1- basins:
[gdal.dataset] raster you create during delineation of a catchment
values of its cells are the number of the basin it belongs to
2- pathout:
[String] path you want to save the resulted raster to it should include
the extension ".tif"
Outputs:
----------
1- raster with only one basin (the basin that its name is 1 )
Example:
----------
basins=gdal.Open("Data/basins.tif")
pathout="mask.tif"
