Won't exit by default in Node

1. Error won't exit the program by default, instead, it will throw an error

In v1.x, when you try to unwrap a Result that is an error, the program will exit by default in Node. In most cases or a strong system, you may want to handle the error by yourself.

In v2, you can set a customized panic function by using the function setPanic. When an error occurs, it will call your customized panic function, then you can handle it somewhere.

class MyError extends Error {}

setPanic((msg: string) => {
  throw new MyError(msg)
})

However, you can still exit the program by specifying the option panic: true.

err('some error').unwrap({panic: true})

NOTE that you should implement the exit behavior by yourself if you are using customized panic function.
