Upgrade Deltacode to use Skeleton and python 3.7+

 * Delete `thirdparty/` and unnecessary files.
 * Delete `Deltacode`, `Deltacode.bat`, `test.csv` and `expected.json`.
 * Change `from bitarray import bitdiff` to `from bitarray.util import count_xor`.
 * Upgrade bitarray to support python 3.7+.
 * Added dependencies in `requirements.txt` and `requirements-dev.txt`.

+Contributor Covenant Code of Conduct
+====================================
+
+Our Pledge
+----------
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our
+project and our community a harassment-free experience for everyone,
+regardless of age, body size, disability, ethnicity, gender identity and
+expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+Our Standards
+-------------
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+-  Using welcoming and inclusive language
+-  Being respectful of differing viewpoints and experiences
+-  Gracefully accepting constructive criticism
+-  Focusing on what is best for the community
+-  Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+-  The use of sexualized language or imagery and unwelcome sexual
+   attention or advances
+-  Trolling, insulting/derogatory comments, and personal or political
+   attacks
+-  Public or private harassment
+-  Publishing others’ private information, such as a physical or
+   electronic address, without explicit permission
+-  Other conduct which could reasonably be considered inappropriate in a
+   professional setting
+
+Our Responsibilities
+--------------------
+
+Project maintainers are responsible for clarifying the standards of
+acceptable behavior and are expected to take appropriate and fair
+corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit,
+or reject comments, commits, code, wiki edits, issues, and other
+contributions that are not aligned to this Code of Conduct, or to ban
+temporarily or permanently any contributor for other behaviors that they
+deem inappropriate, threatening, offensive, or harmful.
+
+Scope
+-----
+
+This Code of Conduct applies both within project spaces and in public
+spaces when an individual is representing the project or its community.
+Examples of representing a project or community include using an
+official project e-mail address, posting via an official social media
+account, or acting as an appointed representative at an online or
+offline event. Representation of a project may be further defined and
+clarified by project maintainers.
+
+Enforcement
+-----------
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may
+be reported by contacting the project team at pombredanne@gmail.com
+or on the Gitter chat channel at https://gitter.im/aboutcode-org/discuss .
+All complaints will be reviewed and investigated and will result in a
+response that is deemed necessary and appropriate to the circumstances.
+The project team is obligated to maintain confidentiality with regard to
+the reporter of an incident. Further details of specific enforcement
+policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in
+good faith may face temporary or permanent repercussions as determined
+by other members of the project’s leadership.
+
+Attribution
+-----------
+
+This Code of Conduct is adapted from the `Contributor Covenant`_ ,
+version 1.4, available at
+https://www.contributor-covenant.org/version/1/4/code-of-conduct.html
