*Steps to reproduce:*
{code:java}
cqlsh> create TABLE stresscql.sstabledump_test(userid text PRIMARY KEY, c1
list<uuid>, c2 frozen<list<uuid>>, c3 set<text>, c4 frozen<set<text>>, c5
map<text,text>, c6 frozen<map<text,text>>);
cqlsh> insert INTO stresscql.sstabledump_test (userid, c1, c2, c3, c4, c5, c6)
VALUES ( 'id', [6947e8c0-02fa-11e8-87e1-fb0d0e20b5c4],
[6947e8c0-02fa-11e8-87e1-fb0d0e20b5c4], {'set', 'user'}, {'view', 'over'},
{'good': 'hello', 'root': 'text'}, {'driver': 'java', 'note': 'new'});{code}
*Root cause:*
Frozen collection is treated as simple column and it's the client's
responsibility to parse the data from ByteBuffer. We have this logic in
different drivers but sstabledump doesn't have the logic in place. It just
treat the whole collection as a single UUID.
