Now, in the help text, the names of all the supported utilities and
aliases are dynamically generated with the macro so that if new
utilities are added in the future they will get included automatically.
These utilities are printed in table-like format for some "aesthetics".
Before, the `ENUMERATE_UTILITIES` macro only included utilities, and all
the aliases to the utilities were explicitly handled. This patch
combines utilities and aliases into one macro. This has the benefit of
being able to do operations involving both utilities and aliases without
having to choose which group to operate on first. Currently, aliases are
mixed with utilities while maintaining alphabetical sort.
We can always read the basic format information (sample rate, bit depth,
etc.), but we will also print artist, album, and title if available in
the metadata.
