• slightly modified json file of FRExt test suite

[rsanchez87]

All changes look good and it's working,

Just a minimal comment @mdimopoulos , in the script gen_jvt.py, line 300, Do you think that to continue with the standardisation, it would be possible to rename this ts to "AVC" without v1?

Unfortunately we cannot do that because that parameter value is used to construct the URL (https://www.itu.int/wftp3/av-arch/jvt-site/draft_conformance/AVCv1/) where the files of the test suite are located. If i remove v1 it will start failing.
The other test suite don't have v1 because the URL doesn't include it (see https://www.itu.int/wftp3/av-arch/jvt-site/draft_conformance/)
