Model3 with merges

See merge request bramas/spetabaru!18

Remove mappings for all write type access modes excluding maybe-write. In model 3 delete copies used in read after a merge if any other copies have failed.

Erase unrelated copy from copy map after creating the delete task (otherwise we create multiple delete tasks for the same copy which causes a double free).

Make sure we collect consecutive dependency slots in getDependencies only if these dependency slots have an access mode different from write or maybe write. Trying to figure out how to properly free copied data after a merge.

Gather all consecutive read dependencies (not only from the same read dependency slot) after a write or maybe write.
