Incorrect pricing for 3.5 Haiku

Hello,

I think the pricing dictionary for haiku-3-5 is not up to date with the anthropic official pricing.

Here is the current pricing dictionary in the source code:
``` python
#| export
pricing = { # model type: $ / million tokens (input, output, cache write, cache read)
'opus': (15, 75, 18.75, 1.5),
'sonnet': (3, 15, 3.75, 0.3),
'haiku-3': (0.25, 1.25, 0.3, 0.03),
'haiku-3-5': (1, 3, 1.25, 0.1),
}
```

But here's the pricing from the anthropic official [pricing](https://www.anthropic.com/pricing#anthropic-api):

I can fix this really quick if this needs to be fixed, unless I'm wrong about this.

Locate the pricing dictionary shown in the issue's source code and verify the current Anthropic API pricing for haiku-3-5. Update that model's pricing values if the report is correct, then confirm the dictionary reflects the official input, output, cache-write, and cache-read rates.
