Provide APKs with each release

Is your feature request related to a problem? Please describe.

First of all, thank you for providing f-droid version, it's great that we have this option besides proprietary Google store. As a further improvement, I'm wondering whether you could also provide apk to download here on the github releases page?

Some reasons why I think it might be beneficial:

• There are tools out there that could use it like Obtainium.
• Some people would like to avoid another middle man they need to trust and get the apk directly from you.
• The apk would be available straight away with the release without the build delay f-droid usually has
• Perhaps it would be possible to provide version with push notification as the build would be in under your control? Not entirely sure if there are any other blockers preventing this.

Describe the solution you'd like

A CI configuration that will build and publish apk when release is made.

Describe alternatives you've considered

Obtainium can also fetch apk from any webpage, so in theory you could publish the apks somewhere on your site, though I think keeping it with source attached to a release makes most sense.

Obtainium can also use f-droid as a source, however some issues (like delayed builds, having to trust 3rd party,..) would still apply.
