Suggest clojure.java.io instead of java.io.* classes

Could suggest:
io/file instead of (File.)
Use of stream functions instead of Java streams
io/reader and io/writer

Start by reading Kibit's existing suggestion rules and entry points for Java interop checks; the issue names clojure.java.io replacements for File, Java streams, readers, and writers. Done means the relevant java.io.* forms produce suggestions for the listed clojure.java.io alternatives, with matching tests added or updated where the existing rules are tested.
