This adds an alternate Dockerfile and start script for an alpine-based image using the official alpine icecast package.
Building upon alpine not only reduces the image size (from 229MB to 11.6MB) but also the attack surface.
For the current image, trivy reports 239 vulnerabilities (5 of which are critical, 54 high) whereas the alpine-based one is only affected by 4 medium ones.
