Refactor condition checks using skipFinder function

Replaced direct temp value checks in 'pool.go' file's two code blocks with a newly created 'skipFinder' function. The 'skipFinder' function encapsulates the conditions, making the code easier to read and maintain. This function checks whether the tweet finder should be skipped based on temperature criteria.
