Octofludb

===================

* Add monthly report generator (used for WGS selections)
* Standardize subtype handling (see runtest `get_subtypes` tests)
* Replace "VTX98" with "LAIV" in internal gene parser
* Add header to `octofludb make const` output
* Add handlers for working with unpublished data
* Convert internal gene clades to uppercase

======

* Add options for updating a certain number of months to `update_gb`
* Add maxyear option to `update_gb`
* Fix bug in `update_gb` that prevented updating of pre-2000 data
* Fix handling of segment subtypes
* Determine strain subtype using octoFLU info

======

* in `update_gb` - work backwards through months, not just years

======

* new subcommands:
* `update_gb`: add missing genbank entries
* `const`: generate constellations for all swine strains
* `masterlist`: generate the A0 masterlist used in NADC quarterly/annual
reports and octoflushow

* cleaner strain name parsing:
* require two forward slashes
* remove parenthesis/bracket terms, for example:
"A/wherever/2020 (H1N1)" --> "A/whereever/2020"
* replace space with underscores, for example:
"A/South Dakota/2020" --> ""A/South_Dakota/2020""

* improved data extraction from genbank records
* link parental strains to genbank segment records
* link strain info to the parental strain, including:
* host - with new cleaning
* country - with new cleaning
* A0 numbers - for USA strains
* states - for USA strains
* collection date - as string literal
* fix incorrect (s, length, locus) link
* convert `create_date` from string literal to date
* convert `update_date` from string literal to date
* convert `length` from string literal to integer

======

* Update patterns for global clades
* allow "Other-Equine" and such
* allow lowercase letters after "3.XXXX."

======

* Add first recipe - a subcommand for getting all constellations
* Allow the constellation MIXED and allow X for unknown clades
