The diffoscope maintainers are pleased to announce the release of diffoscope
version `64`. This version includes the following changes:

```
[ Chris Lamb ]
* Avoid shelling out to colordiff by implementing highlighting in Python
  directly.
* Split out trydiffoscope client and binary package from main diffoscope
  repository so that it can be more-easily released on PyPI.
* Memoize calls to ``distutils.spawn.find_executable`` to avoid excessive
  stat(1) syscalls.
* Remove temporary profiling file introduced in 97bddd18a.
* comparators.directory:
  - Correct `source` attribute of lsattr-based Difference instances.
  - Add comment regarding why difficult to optimise calls to lsattr
* Internally guarantee to all progress observers that we will be processing
  something.
* bin/diffoscope:
  - Ensure that running from Git always uses that checkout's modules.
  - Use os.path.join "properly" as we are already using it.
  - Use typical sys.path.insert(0, ...) method to modify sys.path.
  - Use immutable tuple over mutable list for clarity.
* comparators.debian: No need to keep .buildinfo file descriptor open.
* Suggest command-line for signing of PyPI uploads.
* Improve documentation of new tests/conftest.py file.
