Naturalist lens

[vttale]

There really should be a way to tell whether you can build a National Park without blowing a ton of faith on a Naturalist just to find out whether you can.

I'm not sure whether a mod can figure this out the same way that actually having a naturalist does it though. I've found some interesting bugs (in unmodded base game) where it won't actually let you build a national park in a particular location when a couple of legitimate sites would overlap (but none are built). As an example, say you have 7 breathtaking tiles 2-over-3-over-2. The Naturalist will only highlight -- and only build -- in one part of that. I'm not sure if it is deterministic, but to continue the example it'll only let you build the national park in the diamond on the right hand side. You can force it to build in the left instead by developing (is possible) the rightmost point of the 2-3-2. I don't know if a lens would be able to tell; maybe it should just show all valid tiles anyway and then the player can work around the bugs with actual placement.

(As a culture player I have a lot of issues with the current state of National Park implementation.)

I'll poke @astog with this one, seeing as he's considerably more practiced with lens implementation

@astog has been poked. Have opened that issue in my repo
