Chunk API and stable readers moved out of experimental

The chunk API and some readers were promoted from rerun.experimental to a new flat rerun.chunk namespace.

The old rerun.experimental names still work but emit a DeprecationWarning and forward to rerun.chunk. They will be removed one release from now — a single-release deprecation, since experimental never promised stability.

Moved to rerun.chunk

Chunk, ChunkStore, LazyChunkStream, LazyStore, StoreEntry, Lens, DeriveLens, MutateLens, Selector, IndexColumn, OptimizationProfile, RrdReader, McapReader (and the Mcap*Info types), plus the reader protocols StreamingReader and IndexedReader.

from rerun.experimental import Chunk, RrdReader  # before
from rerun.chunk import Chunk, RrdReader  # after

send_chunks promoted to the top level

send_chunks moved to the top level as rr.send_chunks, next to rr.send_dataframe.

from rerun.experimental import send_chunks  # before
from rerun import send_chunks  # after

Names that stay experimental

The bleeding-edge readers (Hdf5Reader, ParquetReader, Mp4Reader) and ViewerClient / query_metrics stay in rerun.experimental. Split a mixed import by where each name now lives.

from rerun.experimental import Chunk, McapReader, ParquetReader  # before
from rerun.chunk import Chunk, McapReader  # after
from rerun.experimental import ParquetReader  # after
