support loading config from a parent folder (monorepo)

Hi @egoist!

My project structure has:

+-- project
    +-- packages
    |   +-- library
    +-- tsup.config.ts

When I call tsup from the library folder, it fails to find the config file. I see you’re setting joycon’s stopDir to the current project’s folder:

https://github.com/egoist/tsup/blob/405e165ef7412adf54b9a83248144daa4c13be04/src/load.ts#L44-L55

Would you have any objection to changing that and allow resolve() to traverse the filesystem upward?

export async function loadTsupConfig(cwd: string) {
  const configJoycon = new JoyCon()
  const configPath = await configJoycon.resolve(
    [
      'tsup.config.ts',
      'tsup.config.js',
      'tsup.config.cjs',
      'tsup.config.mjs',
      'tsup.config.json',
      'package.json',
    ],
-   cwd,
-   path.dirname(cwd)
+   cwd
  )

Thanks!
