upgrade clj/cljs version and remove parse-long warning.

[tlonist-sang]

; Warnings in Library Code:
;  parse-long already refers to: cljs.core/parse-long being replaced by: no.en.core/parse-long
;  parse-double already refers to: cljs.core/parse-double being replaced by: no.en.core/parse-double

Now that parse-long is inherently implemented in both clj/cljs (1.11, 1.11.50 onwards, repectively), the parse-long function need not be excluded. After upgrading clojure version,

(:refer-clojure :exclude [parse-long])

This line should be removed.

ah, this was already mentioned in #36. But the warnings persist with 0.4.4?
Do you plan to bump clojure/clojurescript to ver.11?

I don’t see a warning neither in Clojure nor CLJS. It is set up this way so it would work with both old and new versions of Clojure. You suggest to change it so it only works with new ones. Why? What will we be getting?
