Generate a regex based on glob pattern and options This was meant to be using the the fs.walk function but can be used anywhere else. Examples:

Looking for all the `ts` files:
walkSync(".", {
  match: [globToRegExp("*.ts")]
})

Looking for all the `.json` files in any subfolder:
walkSync(".", {
  match: [globToRegExp(join("a", "**", "*.json"),{
    flags: "g",
    extended: true,
    globstar: true
  })]
})
