Breaking Changes

restore synchronization behavior of is_abandoned() (by replacing Arc)

dropping a Producer/Consumer on one thread now synchronizes again with calling is_abandoned() on another thread, independent of Rust version

make ReadChunk::commit()/commit_all() panic-safe (avoid UB caused by double-free)
