(+ help message change in desktop version)

NOTE: this changes default mode in cli export to compressed xml - but this also is the default for embedded mode so IMHO it makes sense to align how export looks by default.

Describe alternatives you've considered
Not really, did the change locally and it works for me :).

Additional context
Encountered some problems when migrating from Confluence draw.io plugin (mx files + separate PNGs) to YouTrack (svg+xml embedded mode) - resolved by batch-converting the files using the REST API.

The uncompressed XML resulted in malformed national chars (didn't want to dig into JS to find where exactly lies an error, the data was supposedly passed as base64 datastream, so all decoding might have been done by drawio ). The compressed XML solves the problem with malformed UTF-8.
