Rewrite get_latest_answers + Fix #36

Fix issue #36 + *readable* variables names

added helper functions:
* check_log_types
* and is_<log_activity>_log(entry)
Rename variables + remove function contract / signature
Fix typo
Fix 2nd typo

Hopefully the last one.
Fix bs4 method call + typos
Camel to Snake case + typo
correct casting method name

Using try_cast_int directly in the array is more visual than a map on a two elements list.
