Do you have plan for support AHT content? #151

Hi VoidXH, I was tested some dolby contents such as dolby-atoms-horizon, amaze, leaf. Cavern throw unsupported feature exception "AHT". Do you have any plan for check and and AHT content support?

          The Netflix article is from 2019, but I haven't seen any content from them with variable bitrate. They probably threw the idea away, because it causes many AVRs to recreate the caches and drop sound on each bitrate change. If any AHT content appears, please update this issue.

There is a known issue where if there's any supplementary track with AHT, the reading of the entire file fails. Because Atmos content still has no AHT to my knowledge, its support is not planned, and one workaround is splitting the file to the Atmos track only with FFmpeg, Cavern will decode that. The issue will be fixed soon and separation will not be necessary.

These tracks are identified as actual AHT in Atmos, so the feature has to be added.
