Pass folder path to initialize Tensorboard object

[melihyilmaz]

Changed tb_summarywriter from torch.utils.tensorboard.SummaryWriter to str because we used to initialize the object in config.py but can't do this in config.yaml. Initialization now happens inside Spec2Pep if a folder path is passed.
