Stack creation

Summary

As a user, I want to create a stack from multiple tiff files because I need them to be aligned.

Description

Multiple tif files must be stacked together with gdal in order to have same crs on all of them. This become useful when model needs data for train, it can read different data types from raster bands.

List of steps needed by user story:

1. load input dir from config file
2. sort all tif files (from input path defined inside config file)
3. write sorted paths to temporary file
4. create vrt file
5. create stack from vrt
6. save stack on output dir loaded from config file
7. clean temporary file
