commit 7b42842661aa0be0c3719379ce2804b22feccb44
Author: Carlos Garnacho <carlosg gnome org>

tracker-miner-fs: Separate file data extraction code into its own file
These methods will be handy to keep separate from the main TrackerMinerFiles
code, so we can hook this into the tracker:extractorHash machinery and
trigger re-extraction after code changes.
