Browse source 
* added support for internvl's dynamic high-resolution (Qianfan-OCR needed)

* add min/max dynamic patch to gguf meta

* clean up

* simplified handling min/max dynamic patch

* reuse llava_uhd logic for slice images

* provide default values for older models

* flake8

* prevent writing 0 value to gguf

* remove duplicated resolution candidates with a better algorithm

* fix indentation

* format

* add protection from divide by zero
