Add support for DSRF v1.3

[jamescooke]

Current behaviour

As per the DDEX KB here https://kb.ddex.net/display/HBK/Implementing+Sales+and+Usage+Reporting:

However, when running this validator against the samples provided here: https://kb.ddex.net/download/attachments/950756/DSR-2305%20-%20Draft%20DSR%20Samples%20for%202020%20versions.zip?version=1&modificationDate=1608198989996&api=v2 , an error is received:

python run_dsrf.py /tmp/DSR_PADPIDA00123456743_PADPIDA0123456766K_UnlimitedMusicMonthly_2020-06-01--2020-06-30__1of1_20200703T075930.tsv

Profile Version 1.3 did not match a supported version: ['1.0', '1.1', '1.2'].

Expected behaviour

This validator handles the current v1.3 standard as currently published.

I contacted DDEX. If I understood their response correctly, @jamescooke, this should answer your concern:

New DSR standards are defined in flat-files, not XML files. Therefore, new DSR standards are no longer available in XSD format. Hence, this folder https://github.com/ddexnet/dsrf/tree/master/schemas/BasicAudioProfile might not get a new file (the missing 1.3)

https://kb.ddex.net/implementing-each-standard/digital-sales-reporting-message-suite-(dsr)/

I think this means that the package needs to be updated to read from flat-file standards as it does from XML standards. I'm new to DDEX, but this is something I would be willing to work on if I get some support.

@nielsrump Is there WIP to add support for flat-files in the repo?
