Rainway streaming fails if CbrBitRate is set to 20.0 or higher

[riverar]

Rainway app version 1.0.13.0 Windows 10 1903 18362.1

Repro:

1. Edit %LocalAppData%\Rainway, Inc\Server\settings.json
2. Change CbrBitRate to 20.0
3. Save the file and restart Rainway
4. Start streaming the desktop and note video is black

PWA shows a blank quality profile which may/may not be related.

The labels in that dropdown are associated with specific quality values, none of which match the one you set. That's why it would appear blank. Should have nothing to do with the crash, I'll defer to one of the server devs on that one.
