[FEATURE REQUEST] How is managed geneweb build with dependency on calendar version about geneweb

[Swrup]

Ideally I want to merge calendar-kind and gnt into master at the same time.

Changing calendars master branch can be a problem if you want to be able to build previous version of geneweb.
Because geneweb currently do not specify which version of calendars it needs.
To build previous version of geneweb you would need to "opam pin" the correct version of calendars.

Is that okay for you?
Why do you prefer to build previous version of geneweb?

Thank you @Swrup for the answer.
I want to be able to build 'previous' version of geneweb because we need to continue to support already released versions of geneweb.
So I would suggest to have geneweb to specify what version of calendar to use before to introduce new calendar interface.

PR #1492 specify what version of calendar to use, but this will only work for future commit
