provide a statically linked musl binary for Linux releases

Maybe you guys can consider adding a statically linked musl build (like `x86_64-unknown-linux-musl`)?

Because right now the pre-compiled Linux binary is dynamically linked to glibc so distros like nixos/alpine/etc cannot use it without patches or work-arounds

so a static musl binary wraps all dependencies inside the executable, and making msedit 100% portable and running on any Linux distribution without external runtime requirements

Thanks if you can

Start by reviewing how the Rust project builds and packages its pre-compiled Linux releases, then identify the release entry points responsible for the current glibc-linked binary. Check how a musl target such as x86_64-unknown-linux-musl can be built and published. Done means a statically linked musl Linux binary is available for releases and works on distributions such as NixOS and Alpine.
