`protobufjs` is vulnerable to ReDoS when parsing crafted invalid *.proto files

I would like to report a ReDoS in `protobufjs` It allows to cause Denial of Service by trying to parse (or load) a crafted `*.proto` file.

// awesome.proto
package awesomepackage;
syntax = "proto3";

message AwesomeMessage {
    option (my_option) = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx!;
}
