Context

Beethoven says TVL is $870k but on Dune it is $13M.

Been working on an improvement for the liquidity spell on this query.
Basically, we are exposed to outliers in pricing information that comes from prices.usd and dex.prices. This tends to happen on tokens with less volume of trades.
Therefore, I have created a whitelist for tokens considered as pricing assets (e.g. WETH, USDC, DAI, USDT and a few others). The idea is to have the pool liquidity for weighted pools calculated, whenever possible, based on the balance and price of these pricing assets. This logic can be found on the pool_liquidity_estimates and pool_liquidity_estimates_2 CTEs and accounts for the following cases:

• Pool with only one pricing asset,
• Pool with more than one pricing asset
• Pool with no pricing asset

From my initial analysis, this would have a marginal impact on most chains, with the only exception being optimism, due to the case mentioned in this issue.
I will follow-up on this task by running a PR on the spellbook and checking its impact on our liquidity data.
This PR will be combined with #44, that is to create a macro for the liquidity spells.

that's an interesting approach but another thing we should also do is simply report these outliers to Dune/Coinpaprika. you can send them links or screenshots of the price compared against other platforms (Coingecko)

Will mention distortion on OATH price on my PR and then reference it on dune discord
