Reads the iXML chunk of a wave file, the convention by which field
recorders and the software that handles their files describe a take:
PROJECT, SCENE, TAKE, TAPE and NOTE, among many others that
particular recorders add.
Details
Every element of the document that holds text rather than further elements
is read, named by its own tag, so that fields this package has never heard
of are read as readily as the ones it has. A tag used more than once, as the
entries of a track list use theirs, gives TAG, TAG.2 and so on. The
document itself is kept on the result as its "xml" attribute.

readMetadata() reads this and every other metadata format a file
carries at once.
