Create ts-source-parser package

[jean-michelet]

This PR follows on from discussion #214, which proposes a new package in workspaces for parsing TypeScript files.

Usage example

import { TsSourceParser } from "@nodesecure/ts-source-parser";

const parser = new TsSourceParser();
const body = parser.parse("const x: number = 5;");

console.log(body);

Usage with js-x-ray

import { runASTAnalysis } from "@nodesecure/js-x-ray";
import { readFileSync } from "node:fs";

const { warnings, dependencies } = runASTAnalysis(
    readFileSync("./file.ts", "utf-8"),
    { customParser: new TsSourceParser() }
);

console.log(dependencies);
console.dir(warnings, { depth: null });

You also need to add the workspace in the root package.json

js-x-ray/package.json
