Wez Furlong 1c9bd347c2 multiplexer: improve handling of image attachments ... There were a a couple of issues: * `ImageData::hash` would re-hash the image on every call, and this was called for every cell that comprised an image on the mux server side * `SerializedLine` needed to understand how to remove the `Arc<ImageData>` image attachments so that we didn't serialize a complete copy of the image per cell that comprised the image. A new RPC was introduced to attempt to fetch `ImageData` given its content hash and pane, row and cell index as a hint to locate it. A client side LRU of content hash to `ImageData` is used to avoid issuing repeat calls to that new RPC. refs: #1237		2022-03-28 20:28:05 -07:00
