Investigate human-readable annotation serialization

[gabbard]

It looks like if we serialize using https://uima.apache.org/d/uimaj-2.10.2/apidocs/org/apache/uima/util/CasIOUtils.html we could use a possibly more readable XML-based format

Have you heard of DKPro? Seems to be the same people who made Inception and Webanno. I found this link on DKPro on converting binary to XMI (they are using CasIOUtils underneath). I tried it, and I am attaching an example result of a converted annotation.

It should be easy to add an option to export with the DKPro Core Inline XML writer. But of course inline XML has its limits...
