if replacement audio file is shorter than ad, silence will fall.

[Gavitron]

Setup:

1. download & install adfree APK
2. create a local folder with contents of adfree-resources/*.mp3
3. configure adfree app for:
   • local music

reproduction:

1. play music in spotify

expected result:

1. ads are replaced with multiple "replacement audio" files until spotify music resumes

actual results:

1. when a single "replacement audio" track ends, there is only silence until spotify music resumes

As ads are fairly short, I am personally not planning to add such feature to play multiple tracks in sequence. But I flag it as a feature-request.
