instructions for including weights

[mschrimpf]

Let's tell users how to include weights in the submission.

There are three ways we have recommended so far:

1. If weights are reasonably small (< 1 GB 500MB), you can include them in the zip file
2. Store weights on S3 and download them on-demand. See e.g. the CORnet code for a code sample
3. Store weights on Gdrive, and download on-demand (sample code)

I get the error

413 Request Entity Too Large

for a zip file large 600mb

Thanks @simonepoetto!

We upgraded to a bigger server but are still figuring out how much extra memory it's giving us -- 500MB might be the safer bet for now.
