protobuf.js version: 6.7.0

1. Install typescript@next locally or globally:

npm i -g typescript@next

2. Create empty dir for project, inside make one typescript file:
   import.ts:

import * as protobuf from "protobufjs";
console.log("a");

3. Install protobufjs in above project directory:

npm install protobufjs

4. Compile:
   tsc test.ts

Expected behaviour: compile success

Current behaviour: numerous typescript errors:

node_modules/protobufjs/index.d.ts(419,13): error TS2300: Duplicate identifier 'LoadCallback'.
node_modules/protobufjs/index.d.ts(425,6): error TS2300: Duplicate identifier 'LoadCallback'.

Way to fix: rebuild protobufjs file index.d.ts by pbts but with added option --no-comments

Reason: Typescript using JSDoc data to build types info, but with JSDoc comments typescript use same types twice:

/**

• A node-style callback as used by {@link load} and {@link Root#load}.
• @typedef LoadCallback
• @type {function}
• @param {?Error} error Error, if any, otherwise null
• @param {Root} [root] Root, if there hasn't been an error
• @returns {undefined}
  */
  type LoadCallback = (error: Error, root?: Root) => void;
