Import media

Add an image, video or audio file to the account's media library, so assemble_video and edit_asset can use it: a file the user attached in this conversation (file, where the client passes attachments), a public https link to the file itself (url), or a local file uploaded through create_upload_url (url set to its mediaUrl). Returns the library url. Putting an attached logo in the corner of a video or a picture is this, then edit_asset on the video or picture with an overlay operation whose inputs.image is the returned url and whose config.position names the corner (a picture comes back a PNG). Images up to 25 MB, audio 100 MB, video 200 MB; the type is read from the file, and anything else (SVG, PDF, a web page) is refused. When the user attached a file you cannot pass on (you see it but have no file or link to give), ask them to drop it into their Treza library at https://www.trezalabs.com/chat/assets and find it with list_assets. Needs the pipelines:write scope. Spends no credits.
