Ship Lua 5.1 with default lupa installation

[serozhenka]

There is such a good library as the fakeredis-py, which fully emulates Redis behavior in pure Python. One of the emulated things are Lua scripts, whose execution is done with lupa. However, as the only supported Lua runtime in Redis is 5.1, and 5.x versions are not fully backward-compatible there is breakage when testing scripts and executing them in real-world environments. So there is this suggestion to ship it with default installation along with other versions.

Another valid option might be to ship additional Lua versions by specifying package extras. As an example:

pip install "lupa[lua51,lua54]"

Lua 5.1 will be included in Lupa 2.1.

Try the master branch. The CI build has wheels.
