The 1.0.0 version of this library depends on com.google.android.gms:play-services which is no longer updated by Google.
Fix
In this commit it was updated to com.google.android.gms:play-services-maps however this has not been cut into a release.

Please cut a new release to jitpack.io
Workaround
I haven't tested this but using this snapshot may fix this dependency issue.

I am not sure if jitpack.io provides different POM dependency definitions on snapshots like this which is required to fix this issue.
