modular datomic pulls in old deps and causes breakage

[expez]

modular datomic pulls in datomic-extras which pulls in a really old version of datomic free.

This triggered a hard to debug error when the stracktrace listed under Changes to Index Format here appeared in my console

Obviously, this was the solution

                 [juxt.modular/datomic "0.2.1"
                  :exclusions [com.datomic/datomic-free]]

I see this has already been solved but no new release has been made.
