Connection between sequence_name in metadata and Accession ID in acknowledgement files

[hforoughmand]

Two files metadata data/phylogenetic/metadata.csv and acknowledgement data/phylogenetic/GISAID_acknowledgements.csv lack a common column to be linked. But the more serious problem is that the sequence_name of the samples change in GISAID. For example sequence for sample with name Chile/Talca-2/2020 could not easily be found in GISAID anymore. If the linking information was available, we could use Accession ID to find the right sequence.
