More `Windows` utilities

[vincentsarago]

Rasterio has many windows utilities methods that could be useful also for this project

The ones that comes first in mind are:

• from_bounds: could be a class methods Window.from_bounds(bounds, transform)
• bounds: could be a method Window(...).bounds(transform: affine.Affine)
