oLIB and MLy VOEvents do not have central_frequency and duration values
The content of VO alert voevents are missing `p_central_freq` `p_duration` for MLy, and `p_duration` for oLIB. Fir oLIB is still present the "fluency" that the collaboration has decided not ti distribute.

The code should be changed (my guess to):
```python
elif isinstance(event, LalInferenceBurstEvent):
p_freq = vp.Param(
"frequency",
value=float(event.frequency_mean),
ucd="gw.frequency",
unit="Hz",
ac=True,
)
p_freq.Description = "Mean frequency of GW burst signal"
v.What.append(p_freq)
# Calculate the fluence.
# From Min-A Cho: fluence = pi*(c**3)*(freq**2)*(hrss_max**2)*(10**3)/(4*G)
# Note that hrss here actually has units of s^(-1/2)
# XXX obviously need to refactor here.
# try:
# fluence = pi * pow(c,3) * pow(event.frequency,2)
# fluence = fluence * pow(event.hrss,2)
# fluence = fluence / (4.0*G)
#
# p_fluence = vp.Param(
# "Fluence",
# value=fluence,
# ucd="gw.fluence",
# unit="erg/cm^2",
# ac=True
# )
# p_fluence.Description = "Estimated fluence of GW burst signal"
# v.What.append(p_fluence)
### Duration
p_duration = vp.Param(
"Duration",
value=float(event.duration),
unit="s",
ucd="time.duration",
ac=True,
)
p_duration.Description = "Measured duration of GW burst signal"
v.What.append(p_duration)
elif isinstance(event, MLyBurstEvent):
p_central_freq = vp.Param(
"CentralFreq",
value=float(event.central_freq),
ucd="gw.frequency",
unit="Hz",
ac=True,
)
p_central_freq.Description = \
"Central frequency of GW burst signal"
v.What.append(p_central_freq)
### Duration
duration = event.quality_mean / (2 * np.pi * event.frequency_mean)
p_duration = vp.Param(
"Duration",
value=float(duration),
unit="s",
ucd="time.duration",
ac=True,
)
p_duration.Description = "Measured duration of GW burst signal"
v.What.append(p_duration)
except Exception as e:
logger.exception(e)
