+- new model support: adept/fuyu-8b

 - new model support: MiniGemini-7B -> MiniGemini-8x7B-HD, alternate docker.
 - new openai_example.sh shell script for simple command line generation.
@@ -68,16 +70,6 @@ Version: 0.9.1
 - Fix: moondream1 (use alt container)
 - Split images into main (transformers>=4.39.0) and alt (transformers==4.36.2)
 - Big performance gains (10x) for some models, especially llava-v1.6-34B (`use_cache` missing from many models, all llava* models, more.)
-- new model support: qnguyen3/nanoLLaVA (sub 1B model)
-- Updated chat_with_image.py to include --single (-1) answer mode
-- More testing
-- `sample.env` contains VRAM usage and some notes about model configurations.
-- new model support: MiniGemini-2B (it's still a bit complex to use, see `prepare_minigemini.sh`)
-- new model support: echo840/Monkey-Chat, echo840/Monkey
-- AutoGPTQ support for internlm/internlm-xcomposer2-7b-4bit, internlm/internlm-xcomposer2-vl-7b-4bit
-- Automatic selection of backend, based on the model name
