find_lyra_events() can now find flares in a basic fashion.
CHANGES:
lyra_event_list.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.
Included SAA as artifacts to remove from timeseries before finding flares.
