Rasdapy3 --out string gives error when used with binary data

[apercov]

Running following query

/home/apercov/rasdaman/systemtest/testcases_mandatory/test_rasdapy3/rasql.py --server localhost --port 7001 --user rasadmin --passwd rasadmin --database /opt/rasdaman/data/RASBASE -q 'select c from test_cfloat32 as c ' --out string

I receive the following output:

Rasdapy should print binary data without trying to decode it as Unicode.

rasql.py is just for the systemtests, fixing this behavior is not critical as it's not used in the systemtests.
