Custom-card "Elapsed Time"

This is a custom-card that works with a input_datetime input. Template checks the has_date and has_time attributes and creates a label in x days x hours x minutes ago format.

• x days only included if has_date is true (datetime object)
• x hours only included if has_time is true (datetime and time objects)
• x minutes only included if has_time is true and has_date is false (time object)
