Feature request: `wellbeing_report()` uses custom query

[martinctc]

Currently, wellbeing_report() only runs when there is a custom person query.

An improvement will be to make it possible for this to run using the Wellbeing - balance and flexibility (wb) query template.

Noting that there are the following incompatibilities:

• Workweek_span is a necessary input for wellbeing_report() and is not included in the wb query template.
• Urgent collaboration is defined as urgent email hours in the original wellbeing_report(). In the Power BI template, this uses both urgent email and meeting hours.
• Some slight discrepancies observed between 'Urgent after hours collaboration hours' and 'Non urgent after hours collaboration hours' versus the Power BI template

This issue is resolved in #175.
