* move experiments to new branch&reorganise kv_snapshot * walk&modify tests * added delete from snapshot tests * fmt * state snapshot debug * snapshot validation passed. copy state snapshot * debug * snapshot cursor.Prev test * Prev works correct. Added Current check * add err check * added walk forward and backward test * before refactoring * refactoring * execution with snapshot debug * fix * remove useless test * before dupcursor implimentation * tests with prev and delete works * execution based on state snapshot passed * remove useless tests * blocks to 1140000 passed * clean verifier * cleanup state generation * clean verify && seeder * remove debug code * tests passed * fix lint * save state * test passed * fix lint * add state hash * fix lint
