Use git tags/github releases

[graingert]

It would be nice to host copies of dsfix on GitHub using github releases. This has the advantage of pinning the binaries to the commit hash of the source code.

Running these commands from the command line should do it. Naturally, publishing these requires push access.

git tag v2.2.0 1cb25945740e3e46aad4a9f3e4f69883bb9cd79c
git tag v2.1.0 6f5125cfaf597c4352ad56b14318f82588531921
git tag v2.0.1 301c336d45dd3815de715049d2b0f4ca2ec4da58
git tag v1.9.0 4a406e2a803190cea1bedd78253bcc448ece68d4
git tag v1.8.0 fdd8e34afbe739c326f50756fc3bc8923bd3e45c
git tag v1.5.0 2d67d518e4b3b824b5076dfcd8c9be0db0548b53

I think people use the leading v to help the sort be natural so 10 is after 9 instead of 1

Then to publish them: git push origin master --tags
