create static method

Future<Teemo> create({ int retries = 5, int retryAfter = 5, })

Asychronous constructor for Teemo. Attempts to connect to the LCU retries times, at retryAfter interval.

Teemo will attempt to connect to the LCU websocket, as well as creating an HTTPS rest client instance. Teemo currently only uses the command-line arguments, not the lockfile

Implementation

      ProcessResult psRes = await Process.run('ps', ['aux']);
      List<String> args = psRes.stdout.split(' ');
