Get the pools of a given token address

https://api.dexscreener.com/token-pairs/v1/{chainId}/{tokenAddress}
功能是根据 “链id + baseToken” ，查所有满足条件的池。
比如 https://api.dexscreener.com/token-pairs/v1/arbitrum/0x09E18590E8f76b6Cf471b3cd75fE1A1a9D2B2c2b
就是查Arbitrum链的各Dex中 AIDOGE/quoteToken 这样的池的信息。
看下返回结果中有如下3个。
这3个都是Arbitrum下AIDOGE/WETH，Dex都是Camelot的，1和3号是v2版本，2号是v3版本。
粗略分析一下，从流动性上来看，1号是有效的。 然后有两个v2池是因为camelot v2是uniswap的魔改版，支持定向费用 (Directional Fees) 和不同的曲线类型。
