Enable multi-threading of data delivery (decompress, copy-out, etc.) for read. Including the reads done in finalize.

Speed up range() by using correct type in accumulator. Noticeable when writing int8 or int16 files. Also remove a hand-optimization that didn't have much effect.

Make LocalFileLinux::xx_readv() honor the request for parallel delivery. But don't use the feature yet.

Update Readme.md removing the alpha statements.
