implemented new extention for awaitOps. It fixes several consistency issues (they were previously hard to detect), and it is also pretty efficient. It still has some debugger statements, so enjoy with care

implement new method awaitedOps in favor of awaitedDeletes/awaitedInserts. This will fix some bugs when the type gets out of sync with the state of yjs

all tests working. Fixed an older bug: When gc an op I forgot to update the state. This only affected offline editing, and was very hard to catch in the past

fixed one more problem with ds & fixed ace example & insertions are combined even when created in different execution tasks
