Create a Jackson Databind module to support losslessly encoded tagged values.

This provides both encoders and decoders and is a means of using jsonista to replace something like transit, while still maintaining support for more EDN types. Types are encoded using a JSON list and a customizable tag. For example, :foo/bar would serialize to ["!kw", "foo/bar"] by default, where the first string in the JSON list is a tag for what follows.

(def mapper (j/object-mapper
              {:decode-key-fn true
               :modules [(jt/module
                           {:handlers {Keyword {:tag "!kw"
                                                :encode jt/encode-keyword
                                                :decode keyword}
                                       PersistentHashSet {:tag "!set"
                                                          :encode jt/encode-collection
                                                          :decode set}}})]}))

(-> {:kikka #{:kukka :kakka}} (j/write-value-as-string mapper) (doto prn) (j/read-value mapper)) ; prints "{"kikka":["!set",[["!kw","kukka"],["!kw","kakka"]]]}" ; => {:kikka #{:kukka :kakka}}
