      keys to using manualAtomRemove:
         ilst.ATOM.data or ilst.ATOM target an iTunes-style metadata tag
         ATOM:lang=foo               target an atom with this language setting; like 3gp assets
         ATOM.----.name:[foo]        target a reverseDNS metadata tag; like iTunNORM
                                     Note: these atoms show up with 'AP -t' as: Atom "----" [foo]
                                         'foo' is actually carried on the 'name' atom
         ATOM[x]                     target an atom with an index other than 1; like trak[2]
         ATOM.uuid=hex-hex-hex-hex   targt a uuid atom with the uuid of hex string representation
    examples:
        moov.udta.meta.ilst.----.name:[iTunNORM]      moov.trak[3].cprt:lang=urd
        moov.trak[2].uuid=55534d54-21d2-4fce-bb88-695cfac9c740
