1.2.0

• Refactor Gotify notification functions and improve error handling
• Switch to ghru/v2 for application version checks and self-updating functionality
• Use GitHub Actions to build & package release binaries
• Add dependabot quarterly checks for module updates
• Add code quality checks (golangci-lint)

Please note that this release contains two sets of binaries, tar.gz and bz2. This is to allow older releases to update, and will be switching to only using tar.gz in the future releases. Please just use the tar.gz if you are installing fresh.
