REST/gRPC Data Upload

[gpmidi]

I'm interested in expanding AHDBapp to upload data to a REST API and/or gRPC. Any high level recommendations about how you'd like to see this done? If not I'm sure I can toss something together for this.

I guess whether you push to a db or push to a grpc or rest endpoint is similar

one thing you'd want to do though (and I don't do so far because I rely on the db unique index to fail fast for existing records, it's cheap locally) is first negotiate where to resume the upload from

PR welcome :)
