[PRQ#58700] Deletion Request for rtaudio5-exp

MarsSeed [1] filed a deletion request for rtaudio5-exp [2]: Not a useful package anymore, and not a runtime drop-in alternative of repo's rtaudio (v6). Was created for sdrpp, but that works now with the latter. Also the '-exp' name suffix is meaningless.
