Changed output of find_lyra_events() to a numpy record array.
Changed name of extract_lyra_artifacts to remove_lyra_artifacts.
Removed an errant delete command in extract_combined_lytaf().
Fixed bug in getting correct flux output when calling
remove_lyra_artifacts() in find_lyra_events().
lyra_event_lis.py:

Changed RISE_FACTOR criterion

find_lyra_events():
Fix bug in while loop iteration in

remove_lyra_artifacts():
Fixed bug in removing periods of artifacts which was causing them not to be removed.  This was caused by not understanding that np.logical_and() returns an array of bools.

extract_combined_lytaf():
Fixed how input times were converted to UNIX timestamps.  This was done assuming input times were UTC.

Also fixed how times from annotation files were being converted into datetime objects.  Now use datetime.utcfrom timestamp instead of datetime.fromtimestamp.  The former does not put time into UTC.

Not in lyra_event_list():
Updated lyra, ppt and science annotation files.
