The idea of using url or local picture in the banner_icon

[jianwu111]

Dear author, can you add this function? My idea is that this banner_icon can use this banner's API (function) or use obsidian's official markdown rendering, such as chat view plug-in. Regarding the rendering of Obsidian, we can check whether the text is "http/! [link]/! [[]] ",if we didn't just use this initials to become our banner_icon.
