Our binary increased by 40% due to the introduction of a lot of non-essential code, which could have been avoided. We can no longer use go-selfupdate to do this, but need to implement this in nali itself.

The logic here is simple:

1. Access https://api.github.com/repos/zu1k/nali/releases/latest
2. Compare version numbers
3. Filtering assets by GOOS and GOARCH
4. Download the new version nali and its sha256 via the given browser_download_url
5. Verifying files with sha256
6. Unzip and replace nali itself
