treewide: update to bincode 2

Consistently use bincode's Encode/Decode to avoid issues with
incompatible serde features. Support for storing some temporary files as
JSON is removed.

The size of the "processed" directory is reduced by ~8% with the new
default encoding of bincode 2. Performance is more or less unaffected.
