bhom/wrapped plot methods: return useful information about the plot

[Tom-Kingstone]

Description:

When generating one of these plots, sometimes it is useful to have information about the data behind the plot (time of max temperature as an example). This could simply return some json that has said information contained.

• Calm hours (% of year)
• Prevailing wind direction, and 50th and 95th percentile of wind speed in this direction

UTCI

• Number of hours and % for each comfort band. (Display cold vs no thermal stress vs heat, show % only)
• Provide a 'use hours' input and provide the above, filtered for those hours. (Filter for 07:00-22:59 for now)
