Fixed bug in find_lyra_events where flux at start peak and end times
recorded in output recarray was the scaled flux, not the measured flux.
This has now been corrected.
Manually compute total_seconds of timedelta objects to be compatible
with Python 2.6 which is currently used on p2sc-s2 server.
Rewrote generate_lyra_event_list() function based on lyraff tool.
Introduced warning for when dates are skipped due to
lyra eclipse season and an exception in case all input time range
is skipped for this reason.
Removed erroneous print statements.
