### New Features

 - Add InOrderIter to 'parallel' module
   This iterator makes possible identifies results using a sequence id
   and returns only consecutive items.
   
   Use it to collect unordered results produced by threads.
   It's advantage to collecting yourself and sorting is the potential
   for a smaller memory footprint of in-flight results, one doesn't
   have to collect them all for ordering, necessarily.
 - Make a scope-like abstraction available
   This allows more delicate threading control like is required for the
   index.
 - decoding of variable int numbers.
   It's here only so that we can share the code across crates, for now
   without any feature toggles.
 - Add `progress::Write` to automatically pass bytes written to a progress instance

### Changed (BREAKING)

 - renamed `progress::Read::reader` -> `progress::Read::inner`
