Add stat plots to graphics, UI tweaks

[theastrogoth]

Adds radar plots to each raider in the graphic. The plots use the same format as the ones in PokemonSummary, with small tweaks for readability. These are toggleable, since they might not be desired much of the time.

Also included are some other UI changes and fixes:

• Raider level can be decreased to 0, showing "Any" in the input field and in the graphic. Stats for level 1 are used. This is probably more intuitive than using lv13
• The Gender selection is not reset when changing EVs/IVs

Attempted to fix the issue with stat plots overflowing the boundaries. Using the following sigmoid seems to somewhat mirror how the game handles the plot scaling:

$y\ =\ \frac{1.75}{1+e^{-\left(\frac{x}{125}\right)}}-.75$

Currently, this same function is also used to scale HP instead of having a different HP scaling function which helps for some edge cases (Blissey's plot overflows in-game). The hpModifier can be added back in since that got removed.

Another improvement that can be made is to find a cleaner way to display the text in the plots. I can try a few things later.

I'll try a couple things as well. Plotly might not make it easy without some finagling.

We could also just have a gen 3 style table, if the plots can't be made to look how we want. We'd lose information about EVs, but we would still have those listed above
