New statistics feature for more transparency: A Card distribution per box tab on Pro Kit Box pages

It shows possible deviations from official drop rates. I decided to choose a graphical visualisation instead of mathematical values like standard deviation or variance to make it more intuitive.

Not sure about the name yet, would you prefer something with "deviations" in it?

Here's how it works:
 * Every bar shows the observed numbers of cards a player can obtain from one single box, ranging from the (observed!) minimum to the (observed!) maximum number. "Observed" is stressed because for boxes with a small sample size, it's still possible to get other values.
 * The red line indicates the mean (average number) of cards per box. It doesn't have to be in the middle of the bar. If it's more to the left, it's a sign that a player is more likely to get less of the card, and that the maximum number is possible but less likely, and vice versa.
 * A wide bar means that there can be large deviations from expected numbers. A narrow bar indicates that the number of received cards will be close to the expectations.
 * If there is only a red line without bar, this means that there are no deviations. Min, max and mean values are the same; the drop rates are fixed and guaranteed for every box.

Examples:
 * Most of the boxes with random content look like this. Here, the number of Part cards can vary more than the number of Engines. It is not very likely that a player will receive more than 5 Eninges from a box, but they can be sure to obtain at least 1 Eninge per Box (the official V8 rule is reflected here). The red line without bar for Blueprints is a clear sign that the box doesn't grant Blueprints at all.


 * Large deviations possible concerning the rarity of cards, but the distribution of Blueprint, Enginges, Tech and Part cards is fixed: Players can be sure to get exactly 1 Engine, 1 Tech and 8 Parts from every single box.


 * The opposite of the Daily Kit Box. The drop rates of common, rare and legendary cards are fixed and always the same, while the number of Engines, Tech and Parts can vary to a large extent.

(McLaren 600LT R&D): In good old times, drop rates for R&D boxes were fixed. Now the share of Tech cards is variable which is reflected by the bars for rare and legendary cards. As there are always 4 (rare) Class S Part cards per box (no deviations), players can at least be sure to get 1 Mid-Tech per box. This was at least the case for 6 opened boxes; it's possible that a player also get's 0 Mid-Techs, but 2 Advanced Techs instead. If the sample size was bigger, this case would have most probably been included in the results.
