Reflect truth of min Clojure version required

Although we are testing against Clojure v1.9, was specifying v1.10.3 in
deps.edn as default dep. Now specifying Clojure v1.9.0 in deps.edn as
default dep (and therefore also pom.xml).

Adjusted deps.edn aliases to specifically include v1.10 where
currently needed.

Closes #142
