* Fix the calculation of `areaChecksGotten` to account for flags functionality setting invisible checks.
Change `areaChecksTotal` to dynamic calculation based on tracker visibility, now that all checks are being added to `checksByArea`.
Both are updated in realtime when either "Show all GS locations" or "Hide right side shop items" are toggled.
Reformat all remaining unencapsulated if statements.
* Changed helper variable change and call to `RecalculateAreaTotals()` to when the options are toggled instead of checking every frame.
Removed redundant if...else.
Clarified areaChecksGotten increment/decrement functionality based on current status and incoming status change.
* Removed unused code.
