Individual analysis phases 2+

[Alex-At-Home]

• Incorporate DRtg (with diag) Defensive rating calculation and diagnostics #75
• Add position to sort
• Add O/DRtg adjustments (usage/SoS) (forgot to link to commit)
• Add ability to view possessions as % aa61d76
• Add positional classification Add positional diagnostics to individual stats page #94 and Actually add calculated positional class to the individual tables #95
• Consider switching to DBPM (+ODPM) now that have positional classifications (decided not to)
• Incorporate luck [#100][#59] Individual luck #110
• Stats editor Add stats editor for individuals #112
• Player leaderboard (forgot PR)
• Show approx location in leaderboard
• Use assist rates to get better ORtg (forgot PR)
• Fix Adj Rtg+ to stop doing the weird regression on usage (and possibly make it symmetric either side of 20% usage)
• Adjust AST related credits to take into account "assisted eFG bonuses" for 3P, mid, rim (split into cut-like and post-like)
• Fix DRtg FTR to use actual possession count instead of 0.475*FTA
• ORtg uses globalRosterStats to calculate some images (leaderboard doesn't) for extra regression - but it's not very consistent with how I do things elsewhere

My recollection is that sort needs some work (other than adding position)

Also I had some ideas about improving d-rating, eg incorporating fouls (maybe what types of shots get charged to which positions?) ... but unclear if it's just better to switch to DBPM
