Packaging release assets

[daumantas-kavolis-sensmetry]

1. Currently, release assets are uncompressed, see https://github.com/sensmetry/sysand/releases/tag/0.0.4 for example. I would expect them to be compressed to reduce download sizes, .tar.xz (preferably) or .tar.gz on Linux/macOS, and .zip on Windows (because it only recently gained support for .tar.xz some users may not have up-to-date systems).
2. Executables should not have abi tags, only the downloaded archives. Switching between platforms I would not want to run sysand-linux-x64 on Linux and sysand-macos-arm64, I would expect that sysand would just work on both platforms.

@vytautas-astrauskas-sensmetry It would be good to take care of this in your planned CI refactor.
