Update paymentrequests.proto Was installing electrum on my Kali Linux and when running this command: protoc --proto_path=lib/ --python_out=lib/ lib/paymentrequest.proto i got the following error: [libprotobuf WARNING google/protobuf/compiler/parser.cc:547] No syntax specified for the proto file: paymentrequest.proto. Please use 'syntax = "proto2";' or 'syntax = "proto3";' to specify a syntax version. (Defaulted to proto2 syntax.) Fixed it myself and wanted to share it for people that might have the same issue.
