feat: support multi-part problem responses (FC-0033)

[SoryRawyer]

Responses to multi-part problems are currently excluded from fact_problem_responses because the regular expression for parsing problem IDs was incorrectly handling object IDs for distinct parts of problems. This PR changes the regular expression to accurately parse problem IDs while also removing duplicate problem response records (the first part in a multi-part question seems to have two records for every problem check event).
