More accessible color pallete for muckrock.com/place

[mitchelljkotler]

@eyeseast flagged that the current color palette for /place isn't particularly accessible. We're launching a feature based on a re-crunching of some data, and this seems like a good time to review and update how that's maps are illustrated to make them more accessible. Chris, would you be good for flagging any suggested improvements? I think this should be a light weight fix - we're currently planning the lunch of Alberts piece Monday Dec. 18th, so if possible would love to get updated by then (and if not, at least get it in motion)

Thanks to Chris talking through. For the short term article, we updated to use:

The states where the median cost for records is less than $50 are in green, median costs between $51 to $100 are in blue, and median costs more than $100 are in orange

Green: #66C2A5
Blue: #8DA0CB
Orange: #FC8D62

There's some debate about whether it makes sense to have the stronger division vs. gradation division.

Also semi-related, but some people have trouble finding a given state and it might make sense to offer a state dropdown on that page to make it easier jump to state.

We also want to add the median cost map to the place page, similar to what was statically calculated for Albert's upcoming feature.
