Feature Request: Add target_tokens Setting to Narrow Search Space

[mikewcasale]

Description

I propose the addition of a target_tokens setting that will allow users to narrow down the search space to only focus on some specific tokens. This feature would be immensely helpful in various scenarios where the focus needs to be on particular tokens.

Use Case

The target_tokens setting could be used in filtering, search, or any other operation that requires a specific focus on certain tokens. It would enhance the efficiency and speed of the operation by narrowing down the search space.

Proposed Implementation

The target_tokens setting should be implemented as a comma separated string for @click option integration. When specified, the system would only consider pools which contain target tokens and flashloan tokens.
