Timings

all benches use the uncompressed .json from disk

all done with the "cool an breezy copy" preset

note: the .json is not a perfect fit, bc it is not designed for the Yjs algo (missing parent_right and ids are not perfect)

the json contains: doc size (with tombstones): 182315 doc size: 104852 total inserts: 182315 total deletes: 77463 total ops: 259778

baseline ( just walking through the json, no insertions )
