1、这个接口返回的结果，原值传到 create_add_liquid_psbt 接口 2、因为要根据比例注入，由于 brc20 需要先铭刻，所以不支持创建 brc20-brc20 币对池3、关于 tick_1_inscription_ids 和tick_2_inscription_ids 两个参数的说明。其传值和 coin_type 对应。

• 如果 coin_type_1 是 brc20，则 brc20 inscription_id 放在 tick_1_inscription_ids数组，tick_2_inscription_ids 传空

• 如果 coin_type_2 是 brc20，brc20 inscription_id 放在 tick_2_inscription_ids数组，tick_1_inscription_ids 传空

如果是同一种币对，brc20-btc 和 btc-brc20 创建或注入的是同一个池子（如：ordi-btc，btc-ordi），只是传参使用的字段不同
