This supports creating a composefs image from a simple line-per-file format.
The format used is the same as the one that
composefs-info dumpgenerates, which allows conversion to from textual format. It is also a format that is very easy to produce and e.g. stream to mkcomposefs from other languages.Even though very simple to generate and parse, the format is quite compact. For example, the f36-x86_64-silverblue.json.gz file is 33M uncompressed and generates a 19M composefs image. But the dump file for it is just 16M.
