Add section for "interview" type hints.

[cfbevan]

In Murdle there is a section for statements where the killer is the one lying during the interview. Add a section to the config that will handle solving for the interview statements. They should follow the same syntax as rules but be check one at a time. If give 3 rules you will need to run the full check 3 times. Incorrect interviews will lead to no solutions being found (a contradiction).

• rule1 false, rule 2 true, rule 3 true
• rule 1 true, rule 2 false, rule 3 true
• rule 1 true, rule 2 true, rule 3 false

The output should signify which of the interview rules was false.
