Message of a new event doesn't always show the correct event

Use VOEvent xml directly from gcn notice instead of refreshing grace database.

Make update_all_events asynchronous

Then updating the events will go faster and it will probably close #7.

Add support for cWB.fits.gz files

See for example event S200114f.

Is there a way to extract distance info?
Can the even classification be found anywhere?

Send out updated event when Initial VOEvent is different than the preliminary one

For example event S190727h was classified as a terrestrial event in the preliminary alert, but for the initial one it changed to a BBH.

Show LALInference when available

LALInference is an improved estimation.

Enable viewing of all past events

Currently only the details of the last measured event can be seen with /latest. Add command/interface to view all past events.

Add which detectors saw the event

For example:

Seen by Livingston, Hanford and Virgo.

Duration of status is not in 24h format

The duration on the status status page is not in 24 hour format, but hours keep on adding after 24.

Add link to event page with event message

Send out one new event has been measured even when multiple preliminary VOEvents are send

For example for event S190728q a preliminary event was send 3 times, which lead to the user receiving three messages that a new event had been measured.

Speed up /status command

/status command can easily be sped up by only retrieving the data from the source once, instead of once times for each detector.

Detector status doesn't work when there is an unknow state

Command /status gives no reply when a detector status is in an state without a time.

  File "/root/Projects/GraceDB/gracebot/detector.py", line 44, in __post_init__
    self.duration = self._convert_to_time(duration)
  File "/root/Projects/GraceDB/gracebot/detector.py", line 67, in _convert_to_time
    hours, minutes = time_string.split(":")

Not all events trigger a new event update

For example for event S191213ai I didn't receive a new event message.

Make skymaps prettier

For example making it dark and adding constellations for reference like [here](http://gwcat.cardiffgravity.org/skymaps.

No update message was sent to user when event S190701AH was updated

After event S190701AH was updated user got no message that the event was updated. Probably the origin why #1 stopped working.

Error message after update was requested:

Make /event user independent

If two users try to select an event simultaneously it sometimes skip pages, because the self.start_at parameter in GraceBot class is not unique per user.

Use `async_task` decorator from Dispatcher for handler with long timeouts

/root/venvs/gracedb/lib/python3.7/site-packages/aiogram/dispatcher/webhook.py:206: TimeoutWarning: Detected slow response into webhook. (Greater than 55 seconds)
Recommended to use 'async_task' decorator from Dispatcher for handler with long timeouts.
  TimeoutWarning)

Most likely event type stopped working for event S190701AH

The following error showed when /stats didn't work and /latest didn't show the event type. I think it was after event S190701AH was updated.
