]]> minified into invalid XML

[bmatthews]

I was running some fuzzing tests in an application where i am using this library and discouvered it created invalid xml when ]]> appeared in the xml. while i escape that to ]]> your library then unescapes it back to ]]>

i added this test which outlines my assumption.

diff --git a/xml/xml_test.go b/xml/xml_test.go
index 03e5779..603b77e 100644
--- a/xml/xml_test.go

                // go fuzz
                {`</0`, `</0`},

Note i worked around this for my use case by calling

delete(xml.EntitiesMap, "gt")

that obviously removes some valid minifications though
