I can't get it to use the simplematchers without them having opinions about how sections should open and close, so for now, let's just do some hacks.

fix the way in which simplematchers are invoked: Extract only the stream of json, not the surrounding headers and other decorations.

emit parserstarted/finished events.  Also, reenable some of the non-parsed quantities so the test runs correctly.  However not everything is enabled yet.

include new version of ase octopus parser because it is not out yet.  This fixes some Python3 compatibility issues and contains other improvements.

update json generation script to get a particular ordering and format, and to include section definitions.

clean up unused bits.  Move common functionality into new util module.  Write different parser log outputs to different files.  Convert metadata to correct datatypes and get exact metadata names right (case sensitive)

new parser.  This parser should control parsing of multiple files and call the old one amongst other things.

test are failing though...
