Parses and imports logbooks in all their wonderful confusion

# it can be checked up later from the hard-copy if necessary; or it's not possible to determin (name, trip place, etc)
'''
todo='''
- refactor everything with some urgency, esp. LoadLogbookForExpedition()
- remove the TROG and lbo things since we need the database for multiuser access? Or not?
- profile the code to find bad repetitive things, of which there are many.
- far too many uses of Django field dereferencing to get values, which is SLOW
- Logbooks 1987, 1988, 1989 all crash on MySql - but not sqlite - with db constraint fail. Edit logbook to fix.
- import/parse/re-export-as-html the 'artisanal-format' old logbooks so that
we keep only a modern HTML05 format. Then we can retire the old parsers and reduce the
volume of code here substantially.
- rewrite to use generators rather than storing everything intermediate in lists - to reduce memory impact.
- We should ensure logbook.html is utf-8 and stop this crap:
file_in = open(logbookfile,'rb')
txt = file_in.read().decode("latin1")
- this is a slow and uncertain function: cave = getCaveByReference(caveRef)
- use Fixtures https://docs.djangoproject.com/en/4.1/ref/django-admin/#django-admin-loaddata to cache
data for old logbooks. New design needed, with a mechanism for flagging fixtures as outdated after edits.
