Re: [quicwg/base-drafts] QPACK [editorial] update RIC and Base on figures (#2935)

[afrind <[e-mail]>]

This confusion comes from when we changed Absolute Index to start from 0, and Base *Index* became just "Base".  What is Base now anyways?   Base is now a *Count*, and perhaps we should rename it to Base Count everywhere.

Because Base is a Count and not an Index, it shouldn't really point anywhere in the diagram.  Maybe we should remove the arrow entirely, and just say, `Base = n - 2`

If we really have to have an arrow, then where should it point when Base = Required Insert Count?

Required Insert Count = 2
Base = 2

```
Base
  |
  v 
  | 1 | 0 |   # Absolute
  | 0 | 1 |   # Relative 
```

or

```
Base
  |
  v 
    | 1 | 0 |   # Absolute
    | 0 | 1 |   # Relative 
```

Or when Base is 0 ?


Required Insert Count = 2
Base = 0

```
      Base
        |
        v 
  | 1 | 0 |   # Absolute
  | 0 | 1 |   # Relative 
```

or

```
        Base
          |
          v 
  | 1 | 0 |   # Absolute
  | 0 | 1 |   # Relative 
```
