Add H7N6 build

Requires custom data via fauna to be present in the `ingest/fauna/data`
directory.
Reference genomes are from H7N9 and should be improved.

Ingest:

```
cd ingest
snakemake --cores 1 -pf all
```

Phylo:

```
snakemake --cores 4 -pf -s gisaid/Snakefile --configfile config/h7n6.yaml
```
