- Increased decoding throughput by 3—30% depending on CPU and data.
- Added `{encode,decode}::Configuration` as builder types for their respective
  module. They can be cheaply cloned.
- Added `decode::Configuration::with_yield_on_full_buffer` to explicitly opt-in
  to libtiff compatibility. The decoder will not read or interpret further
  symbols of the decoding stream when the output buffer is full. This enables a
  caller to stop fetching symbols and elide an end of stream marker based on
  out-of-band length information. The decoder might otherwise error, trying to
  interpret data that does not belong to the stream.
