Review Comment:
   Currently yes, the `hambra/avro` library doesn't return the field-id back to 
us at all. 
   
   I think I can possibly leverage the 
https://pkg.go.dev/github.com/hamba/avro/v2#Schema object in the library to get 
the field-id property but I haven't spent enough time there yet to work out the 
best way to handle it.
