Add a way of importing CAR files (for backfilling)

[alnkesq]

I already have some draft code, but it compiles against an old version of FishyFlip, and migrating would require a replacement for ATRecord.FromCBORObject (which no longer exists or isn't public)

I don't believe you should need that.

https://github.com/drasticactions/FishyFlip/blob/develop/src/FishyFlip/Tools/CarDecoder.cs#L26

CarDecoder.DecodeCar takes in a CAR and decodes it into record files which get exposed via OnCarDecoded as events. That would get you the ATObject's that exist within a CAR file.

You could also do what the Firehose code does (https://github.com/drasticactions/FishyFlip/blob/develop/src/FishyFlip/ATWebSocketProtocol.cs#L200-L259)

using var blockStream = new MemoryStream(e.Bytes);
var blockObj = CBORObject.Read(blockStream);
if (blockObj["$type"] is not null)
{
    message.Record = blockObj.ToATObject();
    this.OnRecordReceived?.Invoke(this, new RecordMessageReceivedEventArgs(frameCommit, message.Record));
}

You can create a CBORObject with CBORObject.Read and use .ToATObject(); to turn it into an ATObject.

If you need something else, feel free to file a bug.

You're right, ToATObject is what I was looking for.
