Add Overwatch League skins to each hero

[TheTural]

Adds OWL skins to each hero's page. Calculates totals correctly and has the skins list collapsed by default (because it's a long list and looks bad to be always on the page).

I've also included a python script I wrote that adds the necessary data directly into master.json - It would definitely be better to just handle the generation of owlskins info when doing the initial parsing of game data, but I didn't have a rawData.txt to work with and didn't know where to get one, so I wrote the python script as a brute force way of adding the data to master.json

I have a fork of this that is live here for viewing/testing: https://thetural.github.io/

I just realized that this makes some superfluous changes. Not sure how that happened, but probably due to my github incompetence. I merged the current Master branch to my fork, then did the PR off of that.

These don't need changes from me:
css/_global.scss
css/main.min.css
data/events.json
helpers/dataMapper/EVENTDATA.js

Nice work putting this together, I'll likely pull this locally and use some of the work you've done and make some changes.

I gotta be careful with OWL stuff because because there are 12 teams + the OWL Team, then there is away team versions of every skin, soon there will also be contenders skins + away. Not to mention there will also be 6 new OWL teams next year.

I mostly wanna think about how I want the data to be structured, adding 28 (34 next year) skins to every hero is just a massive bloat to the json when they're essentially all the same.

My suggestion would be to put all the OWL league skins in their own page (like the event ones), divided either by teams or by heroes. When one of those skins is marked as owned, the hero's page would update, showing it in the list and updating the value. If it can't be shown in the list, then just update the value.
