          feat: support fastlanes bitpacking (#2886)

681db8c

This PR uses [fastlanes
algorithm](https://www.vldb.org/pvldb/vol16/p2132-afroozeh.pdf) for
bit-pack encoding.

The bit-packing routine is migrated from [SpiralDB's fastlanes
implementation](https://github.com/spiraldb/fastlanes), the migrated
code is modified to allow rust stable build.
