    voice:  Include a simple string enumeration in voicestrings.zip
    
    This maps the numerical IDs contained within the binary .vstrings files
    to their logical LANG_* and VOICE_* names.
    
    While not strictly needed to produce voice files, it adds the final
    piece to be able to use vstrings files to produce the same voice files
    as the existing 'make voice' flow that directly parses the language files.
    
    The 'make voice' flow intentionally divert a few of the generated clips
    into standalone files:
    
     * "invalid voice file"
     * <spoken language name>
     * <short pause>
    
    For this to be possible, we need to know which specific entries in
    vstrings map to the ones we care about, and without this enumeration
    (which can change on a per-target or even per-build basis) this is
    effectively impossible.
    
    The produced lang-enum.txt is simple, with one entry per line of the
    format: number:name
    
    Note that nothing uses this new file yet; that will come in subsequent
    commits.
