[TIKA-1247] WIP: Exploded parsers: asm, audio, chm, html, txt

This is a WIP still, as the parsers exploded are NOT
removed from tika-parsers monolithic module (yet).

Am not an OSGi expert, and am unsure will this work at all? Or maybe just explode them in "plain" JARs and then make the existing tika-parsers reassemble the parsers in a bundle?
