Add spot packages to popular linux distributions

[umputun]

The existing packages we produce, deb, rpm, and apk, currently allow direct installation. However, I recognize the potential value and convenience of having our software included directly in Linux distributions.

Upon investigating the necessary steps, it appears the process is somewhat involved. For instance, Debian requires one to be an approved maintainer, a process that entails nomination by an existing maintainer and the successful completion of a series of checks.

While I understand the rationale behind these requirements, I have decided not to pursue this route. Instead, I'm keen on partnering with an existing maintainer who could handle the submission process for us.
