Including the past USACO problemsets

[stefdasca]

The United States Computing Olympiad (USACO) is a prestigious coding competition with tens of thousands of contestants competing every year.

Given the relatively archaic state of the USACO website (occasional downtimes, together with an outdated UI), having the past problem sets from this competition would greatly benefit both the USACO audience as well as the website itself, as we would have a more diverse problem set, with over 500 problems of various levels (Bronze to Platinum) on the website together with the editorials and the test data would be an excellent addition.

Definitions of done

• having the problems uploaded to the website and categorized by year and division
• having problem editorials and external links from and to Kilonova @stefdasca
• allowing submissions using Java programming language as per another issue mentioned here
• allowing larger time limits (2x for Python and Java) for slower programming languages

I think to make it worth while we can use some form of import script. One thing I noticed on the usaco website is that while the ui is in a bad shape it's quite easy to scrape quite a lot of the data including the markdown.

I've played around with Obsidian Web Clipper[0] and it extracted markdown quite well(even the latex). Of note is that the latex is using mathjax
