================================================================
this function prepare downloaded raster data to have the same align and

and return a folder with the output rasters with a name "New_Rasters"
Inputs:
1-Raster:
[String] path to the spatial information source raster to get the spatial information
(coordinate system, no of rows & columns) A_path should include the name of the raster
and the extension like "data/dem.tif"
2-InputFolder:
[String] path of the folder of the rasters you want to adjust their
no of rows, columns and resolution (alignment) like raster A
the folder should not have any other files except the rasters
3-FolderName:
[String] name to create a folder to store resulted rasters
Example:
Ex1:
dem_path="01GIS/inputs/4000/acc4000.tif"
