Updates for 3.4: new xx-template for roll, archived 33 test data

[iherman]

In preparation for 3.4 testing, this PR

• archives the epub3.3 test results, report template and opds file. The template and opds files are removed from the repo (they are now generated by github actions on-the-fly). For the time being the old test results are kept; they should, eventually, be replaced by new test results
• renamed the fixed layout template to xx-lay-pp-template, and created an xx-lay-roll-template
