Add functionality from #10 to TS branch

Sorry to pester you again :)
I am getting the following error.

PS C:\Users\ DummyMe\Desktop\New folder> node main
Notion Export Path:
A
readline.js:1147
            throw err;
            ^

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of Buffer or URL. Received undefined

    at ReadStream.onkeypress (readline.js:205:10) {
  code: 'ERR_INVALID_ARG_TYPE'
}

PS. I ran the old main.js it worked fine (not the table linking, but ran)

@dummifiedme That is a separate problem from this issue. I'll make a new issue for that.

Closing this issue because the TS branch is out of date and needs to be written from scratch.
