Fix ComplexInput.from_json to handle data_format.encoding="base64"

[gschwind]

Overview

Fix the serialization/de-serialisation of input data when they are binary and base64 encoding.

Add the corresponding test.

The issue may be triggered when the binary file is send using base64 encoding within the XML request as instance:

    <wps:Input>
        <ows:Identifier>someidentifier</ows:Identifier>
        <wps:Data><wps:ComplexData mimeType="application/zip" encoding="base64" >
            SOMEDATA IN BASE64
        </wps:ComplexData></wps:Data>
    </wps:Input>

Note I did not actually checked the issue, I just triggered it with test case in the patch series.

@gschwind there is now a conflict in the tests after merge of #651 . Could you resolve it? I will merge it then and make a new patch release of pywps.

Hello,

I did a rebase and solved the conflict.

Best regards.
