// Upload generically uploads data from `reader` as an asset to the ROBLOX
// website. `info` can be used to specify information about the model. The
// following parameters are known:
//
// type - The type of asset.
// assetid - The id of the asset to update. 0 uploads a new asset.
// name - The name of the asset.
// description - The asset's description.
// genreTypeId - The asset's genre.
// isPublic - Whether the asset can be taken by other users.
// allowComments - Whether users can comment on the asset.
//
// The success of this function is highly dependent on these parameters. For
// example, most asset types may only be uploaded by authorized users.
// Parameters that specify information about the asset only apply for new
// assets. That is, updating an asset will only update the contents, but not
// the information about it.
//
// `assetVersionId` is the version id of the uploaded asset. This is unique
// for each upload. This can be used with GetIdFromVersion to get the asset
// id.
//
// This function requires the client to be logged in.
