Release v3.0.0

Changed

• Full option names are now spelled out in the kebab-case.
• The --target-format option now accepts a single value, but you can specify the option multiple times to pass multiple values. For example, the equivalent of the default: -f avif -f webp.
• In files generated by the --add-meta-data option, the sizes array is now sorted from smaller breakpoint to larger. The size without a breakpoint is still placed at the end of the array.
