version 1.4.0

Changes since 1.3.3:
- The C implementation provides a `CMakeLists.txt` for callers who build
  with CMake. The CMake build is not yet stable, and callers should
  expect breaking changes in patch version updates. The "by hand" build
  will always continue to be supported and documented.
- `b3sum` supports the `--seek` flag, to set the starting position in
  the output stream.
- `b3sum --check` prints a summary of errors to stderr.
- `Hash::as_bytes` is const.
- `Hash` supports `from_bytes`, which is const.
