Title: Feature/screen by iso

Inserts a step in the workflow to allow screening pixels by country, using gadm id and a set of iso codes. This could be inserted at the beginning to reduce overall processing time by reducing the overall number of pixels to only those inside specific countries.

Brazil, for example, is covered by a number of tiles that also cover much of the forested area of its neighbors. Since at the moment we need data for specific countries ASAP, this will help us deliver data quickly because any pixels that are outside Brazil would be dropped.

This is really only relevant when we're doing a subset of countries as we are right now. Once FORMA is fully automated for the full tropics, this step need not be included.
