Removal of old versions from maven central

[BenniHackstock]

Is there a concrete reason for always only having the latest version of the library published on maven central?

Removing the old version after the new one has been published frequently breaks compilation and forces us to update the dependency declaration.

This is no big issue for apps, but as we use the library in an sdk, we need to include the webrtc-sdk as aar, to avoid having to release new library versions when the old webrtc-sdk version cannot be resolved anymore.
