How to Update whatsapp.proto to The Latest Version?

You can update it by extracting from web.whatsapp.com with the extractor tool by Sigalor. Check here: github.com/sigalor/whatsapp-web-reveng

Rebuild proto notes Some Protobuf Builder ignore the syntax=proto2, so I need to enhanced whatsapp.proto like this:

# from 
repeated uint32 scanLengths = 22;
# to
repeated uint32 scanLengths = 22 [packed=false];

and also I modified generated ts file manually, because protoc-gen-ts has problem dealing with repeated integer fields on protobuf version 2. this the patch:

# REPLACE
message.scanLengths = reader.readUint32();
# WITH
pb_1.Message.addToRepeatedField(message, 22, reader.readUint32());

I have replaced it in build.sh using sed.
