Elixir Version for ex2ms about ex_rated

[grempe]

OK, ex2ms was finally updated and pushed to hex.pm. I was able to fix the dependency issue in newly pushed ex_rated v1.3.1

https://hex.pm/packages/ex_rated/1.3.1

Sorry, I take that back. hex.pm will not allow me to push a new version of the package that depends on a git repo. I had to revert the commit that pinned ex2ms to git.

This appears to be a problem with the ex2ms package on hex.pm See the bug report here:

ericmj/ex2ms#12

And the commit that seems to be the root cause here:

ericmj/ex2ms@8d6f13a

@MSch will need to resolve this I believe.

I have updated the ex2ms dependency to pull directly from github until that project finds the person that can push a new release to hex.pm. The updated ex2ms also fixes some compilation warnings.
