Build wheels on earlier OS versions & verify binaries are included

[paddyroddy]

Add an additional step which installs the latest from TestPyPI and creates a BayesianTracker instance to verify if the binary is included. This then leads to a step which only uploads to PyPI.

To test in docker locally, I am running the following https://github.com/quantumjot/btrack/issues/296#issuecomment-1511006705

[paddyroddy]

I'm going to try a few more things. Reverting back to draft.

[paddyroddy]

Okay, so I've tried a few things:

• I've investigated whether we can build the binaries for mac on linux (doesn't work).
• I've looked into supporting earlier than macos-11 and in reality we cannot. GitHub did have macos-10.15 but it has been deprecated. We will have to state that we do not support older architectures. Given that 11 came out on 12 November 2020 I don't think this is unreasonable (see https://en.wikipedia.org/wiki/MacOS_version_history#Releases).
• I've looked into supporting earlier than ubuntu-20.04 and in reality we cannot. Even the manylinux container project only supports from 20.04. In theory, this wheel should work on any distro, although we cannot completely guarantee that.
• Regarding different architectures (i.e. ARM/intel), there are ways to do it, but not trivial. For M1 mac specifically, we're blocked any as cvxopt still doesn't have ARM wheels cvxopt/cvxopt#234 (this has blocked me). The GitHub runners are all x86_64 https://github.com/orgs/community/discussions/25319#discussioncomment-3247468. If we can get cibuildwheels working #235 then this should be possible.

Ready for review @quantumjot @p-j-smith

[quantumjot]

Looks good to me - although I have to admit that the level of workflow wrangling here is beyond my comprehension.

Regarding the supported versions, I think this is fine. One of the reasons why btrack<=0.5.0 worked for others may be that we built against an earlier version of Eigen using C++11. Do we want to add a line to the README to indicate this change?

[paddyroddy]

Have added a comment on Eigen
