Crash when overriding normal METAR fetch

[nicelion]

When attempting to manually update a station's METAR, as can be seen in the example from the documentation site, a crash occurs.

>>> from avwx import Metar
>>> ksfo = Metar('KSFO')
>>> report = 'KSFO 031254Z 36024G55KT 320V040 1/8SM R06/0200D +TS VCFC OVC050 BKN040TCU 14/10 A2978 RMK AIRPORT CLOSED'
>>> ksfo.update(report)

I am getting this crash on both MacOS and Raspberry Pi OS after a fresh install of avwx.

Hmmm. Looks like the documentation hasn't been building lately. Need to figure out why.

In the meantime, report parsing has been given its own method:

from avwx import Metar

ksfo = Metar("KSFO")
report = "KSFO 031254Z 36024G55KT 320V040 1/8SM R06/0200D +TS VCFC OVC050 BKN040TCU 14/10 A2978 RMK AIRPORT CLOSED"
ksfo.parse(report)

print(ksfo.data.flight_rules). # => "LIFR"

Awesome. Thank you for your help.
