[h4ck4l1]

@andrei-ng please notify any changes, I am unsure when I will respond next week but I will make sure changes take place atmost in next weeks weekend.

1. I thought of adding everything in binding but callbacks even the next Select callback need their own structs and higher level SelectEvent structs
2. All the fields are Optional as using serdes default attribute gives serialization error for reasons beyond me.
3. Added the minimal Yew example
4. If this goes through implementing select,hover and rest are on the way

No worries. I have been lurking between wasm, dioxus and this repo and found something more breaking

I've raised this in #4071

in yew this might not be a problem but in frameworks like dioxus SPA the scripts loading takes a bit time and plotly actually takes more time that other frameworks, so when i am using other 3rd party libraries and functions using wasm_bindgen they are giving me an unreachable error. that why i am currently having to inject scripts manually before the calling of new_plot i don't think this will effect yew but for dioxus it will imo, if one uses more that 2 or 3 scripts. please check the issue if you have the time.
Right now i am using 2 external js libraries plotly and datatable and both of them actually require injecting js_scripts if the page is to work after a refresh.
