Get a weights upload slot

Returns an upload slot for one file of the weight set you will put. Upload the bytes with an HTTP PUT to presigned_url, sending the Content-Type and size you declared. Files are stored once per account by SHA-256, so a file you already uploaded at the same size returns copied: true and needs no upload.

Files up to 5 GiB use this route. Use the multipart routes for larger files. Available when weight sets are enabled for your account. Requires the account_admin or developer role and Serve access.
