Typo in class name "MutliwayEmbedding" #120
Description
In torchscale/component/multiway_network.py line 48, a class named MutliwayEmbedding is defined. This should be MultiwayEmbedding ("Mutli" vs "Multi").
This is also referenced in /torchscale/model/BEiT3.py lines 13 and 33. I have the fix as a commit on my local device, but don't know how to push it upstream (I keep getting permissions issues and suspect there's a process for getting my branch pushed up).
