Generate Historic Data, Showing In Simple Table

[vkoves]

Description

Updated the data process to generate a new benchmarking-all-years.csv, which contains a smaller set of columns with historic data, so we can see emissions and energy use change over time, and adds a simple table view to render this data. This isn't elegant, but is better than not having the data at all.

Demo From Merchandise Mart:

Note: Only columns with any values will be rendered, to reduce noise. So for Merchandise Mart, the Energy Star Score or District Heating is not shown over time.

Resolves #73

Testing Instructions

Confirmed that historical data renders properly on a variety of pages - even if a building only has one year of data, the table should render fine. Also made sure the table works well on mobile by scrolling it horizontally.

Idea for improvement: Hide columns that never have data (e.g. the Energy Star Score in the PR description screenshot from Merch Mart) since there's no point comparing something with no data at all.
