Investigate version detection of EGM protocol

[gavanderhoorn]

With the requirement of using at least version 6.07.01 of RobotWare in #32, we've had a few reports of users running into issues when trying to use an older version of RW (see #42 and #45).

It would be good if abb_libegm supported some sort of version check, as this could help us print an error message if/when an incompatible version is being used.

With a wider range of RW 6 versions available now, the potential for unexpectedly running into an incompatible RW version has increased.

Have you had any time to look at how to implement some form of version detection @jontje?

Not yet, but I have an idea of how to do it.

I have a couple minor PRs prepared after this one #63, and after that I am working on another related to RW6.10. I can investigate about version checking in that one.

@jontje: friendly ping again :)

We have even more RW6 versions now then when I wrote #46 (comment), so this may be something valuable to have (ie: the ability to detect versions, and block incompatible ones).

Thanks for the reminder 😃
