{@link PARSE_MODE#RMETA} "recursive metadata" is the same as the -J option
in tika-app and the /rmeta endpoint in tika-server.  Each embedded file is represented as
its own metadata object.

{@link PARSE_MODE#CONCATENATE} is similar
to the legacy tika-app behavior and the /tika endpoint (accept: application/json) in
tika-server.  This concatenates the
contents of embedded files and returns a single metadata object for the file no
matter how many embedded objects there are; this option throws away metadata from
embedded objects and silently skips exceptions in embedded objects.
