thanks a lot for this PR, here are some suggestions:

1. I think it would be nice to have a generic component able to work on any image data source not only xview - I think the code might be already doing this
2. can we rename this component to: image-tiling?
3. can you please also add a destination folder parameter (in addition to the source folder)
4. can we rename window_size to tile_size_x and tile_size_y (and also support non-quadratic tiles?
5. in the case of sliding windows we should add a parameter stride_x and stride_y to control how the windows are moving over the source image
6. this is a hard one and might need to be taken into a separate issue, but in geospatial images (also in medical images) there is meta data associated (e.g. in a geotiff) - if you extract tiles from such an image the tile should also have the metadata copied over and adjusted for the new image size (e.g. if you greate a tile from a large satellite image then the metadata should be adjusted to reflect the new coordinates)
