Is there a "fee" field for `PoolDBData`

[ruidazeng]

In the current implementation of the PoolDBData structure, there is no explicit field for representing the fee incurred for swaps or transactions within a pool. The fee is part of the calculations in CFMM routing algorithms based on Guillmo Angeris's work on optimal routing.

Wondering if we can get some data that looks like this (the below one is dummy data made up by me based on Guillermo Angeris' fake examples in his code.

 # Pool information
    pool_info = {
        "pool1": ArbitragePoolInfo(
            pool_id="pool1",
            base_token_idx=1,
            quote_token_idx=2,
            fee=0.997,
            weight_base=0.5,
            weight_quote=0.5
        ),
        "pool2": ArbitragePoolInfo(
            pool_id="pool2",
            base_token_idx=2,
            quote_token_idx=3,
            fee=0.997,
            weight_base=0.5,
            weight_quote=0.5
        )
    }

Or should I make up fees or make them 0.997 0.998

That is a good point. The transaction fee is something that changes and is not baked into the smart contract. Estimating with those numbers would be good. @ruidazeng .
