Pull request type

Please check the type of change your PR introduces: - [ ] Bugfix - [x] Feature - [ ] Code style update (formatting, renaming) - [ ] Refactoring (no functional changes, no api changes) - [ ] Build related changes - [ ] Documentation content changes - [ ] Other (please describe): ## What is the current behavior? Currently `tree_cover_extent_total` is absent from dashboard output. ## What is the new behavior? `tree_cover_extent_total` is present, it describes the area of pixels where GLAD alert has happened that has tree cover density > 30% It also introduces the error columns like FCD gained in https://github.com/wri/gfw_forest_loss_geotrellis/pull/105 that ensure that every record present in the input is present in the output. ## Does this introduce a breaking change? - [x] Yes - [ ] No downstream consumers will have to adjust their code to use the tree cover extent and errors
