Feature: Hint relation between data visualizations

Hint relation between data visualizations

## Purpose
To teach users visually about Simple Serialize.

## Proposal
If the user hovers over sections of the serialized bytes, each minimal block of data is highlighted and matched to the corresponding deserialized representation. Also, a popover can give info about the data type.


## Issues
I believe ssz is run as a black box, so it may not be trivial to get the info required for this visualization. How could this mapping be extracted without coding a secondary deserialization algorithm?

It would be nice to get some sort of "AST" of the serialized bytes to render them as a sequence of inline elements. For example:
```js
[
{
type: "offset",
bytes: "94000000",
path: "aggregationBits",
},
{
type: "fixed",
bytes: "0200000000000000",
path: "data.slot",
},
{
type: "fixed",
bytes: "0400000000000000",
path: "data.index",
},
]
```
