create python script to create data that are usable for evaluation

[elray1]

• latest available sequences covering the date range that was predicted with reference date 90 days ago
• uses the reference tree that was available 90 days ago

can be adapted from https://github.com/reichlab/get-covid-clade-counts/blob/main/get_covid_clade_counts.py

can use code along these lines:

from cladetime import CladeTime, sequence

ct = CladeTime(tree_as_of="2024-08-02")
filtered_metadata = sequence.filter_metadata(
    ct.sequence_metadata,
    # DON'T FORGET TO DO THIS ADDITIONAL FILTERING ON COLLECTION DATES!
    collection_min_date="2024-07-01", 
    collection_max_date="2024-07-03"
)

assignments = ct.assign_clades(filtered_metadata)
