Ranked stats rough draft

[redbeardymcgee]

This PR revisits #3 without a thrashed commit history or zprint-induced whitespace noise diffs.

I have been trying to get this to work for a couple of hours by stepping through a macroexpansion of defparser and manually testing a call to fetch-player-season-ranked-stats, but no luck so far. I could use some nudging toward a solution.

The standard unranked stats returned by fetch-player-season-stats looks like this.

{:body
   {:data {:attributes {
                        :game-mode-stats {:duo {
                                                :assists 0,
                                                :boosts 0,
                                                :d-bn-os 0,
                                                ...<SNIP>},

The ranked endpoint returns this:

{:body
   {:data {:attributes {
                        :ranked-game-mode-stats {:squad-fpp {
                                                             :assists 159,
                                                             :avg-rank 8.719444,
                                                             :avg-survival-time 0,
                                                             ...<SNIP>}}},

The shape of both structures is identical, which I have emphasized with some effort at alignment. From digging in parsers.clj I have concluded that player-season-ranked-stats-parse essentially just does a fancy call to get-in. It uses the vector value of :from to traverse the nested map and sets the value of each key in season-stats-parse, which again uses a :from [:keys] approach. It appears to not know anything more than the fact that :game-mode-stats is a key to a map containing relevant stats data.

Given the fact that the ranked stats data has exactly the same shape, I would expect a first draft implementing ranked stats would be able to safely copy and paste the approach for unranked stats. However, the :season-ranked-stats key result is just an empty vector. I cannot understand why this happens. I'm traversing an identical data structure with an identical approach, but I capture no data.

False alarm. The season ended and changed over while I was working on this PR. Nothing is actually broken -- the ranked stats endpoint just doesn't return any data until the player plays a game I suppose. Unranked endpoint doesn't seem to care whether the player has any match history in the current season.

The response now looks like this:
