dotty - cdot-based position projection

What can it do?

Run it the background, e.g., from main as

$ DATA_DIR=$PWD/data \
    pipenv run uvicorn dotty.main:app --host 0.0.0.0 --port 8080 --reload

Then, resolve c./n./g. variants to SPDI-like variants

$ curl 'http://127.0.0.1:8080/api/v1/to-spdi?q=NM_000059.3:c.274G%3EA' 2>/dev/null | jq .
{
  "spdi": {
    "assembly": "GRCh38",
    "contig": "13",
    "pos": 32319283,
    "reference_deleted": "C",
    "alternate_inserted": "A"
  }
}
