Decoding protobuf message from mapbox API

Hi,

I'm new to the world of protocol buffers, looking for some guidance here.

I have a fairly simple use case which is to decode protobuf messages from the mapbox API into GeoJSON format.

How would I approach this problem? Would I need to define a custom Julia struct according to this mapbox pbf specification? Or is there a simpler, more generic way of decoding the protobuf message into a Dict of some sort.

Essentially I would like to replicate what this python library is doing!

Thanks in advance...
