Panic after WKT commit: assignment to entry in nil map

[coxley]

Using the commit from #99: go install github.com/planetscale/vtprotobuf/cmd/protoc-gen-go-vtproto@d49cd97

Nothing special about the parameters seem to change it:

protoc -Iprotos/protobuf \
  --go-vtproto_out=paths=source_relative,<omitted module rewrites>:gen \
  --go-vtproto_opt=features=marshal+unmarshal+size+pool+clone \
  <protos>

panic: assignment to entry in nil map

My bad. Can you try pulling main again? :)

@vmg So fast — fixed. :)
