What

This moves the copy / save buttons inline next to the component. In order to do this, I've split the blob / image / video uis into structs with a data_ui and inline_button fns. The ExtraDataUi is a wrapper for convenience.

In hindsight this could have probably also been done using freestanding fns.

This also fixes a couple inconsistencies between Image and EncodedImage. Both now show a histogram and both show the image format.

I love this design

I miss some sort of tooltip for the button

Also: clicking the copy button provides no feedback. I would expect a "Image copied to clipboard!" or something. Right now it just feels dead/broken, even though it actually works.

Just a re_log::info will do it 🤷

Looks great! But we need some feedback after clicking the copy button, and ideally a tooltip too
