Failed when parsing time limit and memory limit on UOJ

As I mentioned in #64, there are many irregular time/memory limits on UOJ.

Most time limits are in this regex format: 时间限制(?:</strong>)?(?:：|:)(?:</strong>)? ?\$.*?([1-9][0-9]*).*?\$.

Most memory limits are in this regex format: (?:空间|内存)限制(?:</strong>)?(?:：|:)(?:</strong>)? ?\$.*?([1-9][0-9]*).*?(M|G)B.*?\$.

However, there are still a few problems which don’t satisfy these two rules, and there may be more irregular forms in the future.

I’ve improved the time and memory limit parsing for UOJ in https://github.com/jmerle/competitive-companion/compare/9f0eab3f19c8790db934b605bfe64aca2f88ae7a...197e83c239de0f33c929387c70695b72800003bb. These changes work correctly on all the problems you listed except for 451 and 452 because those problems use a non-standard way of displaying time and memory limits. In case it fails to parse the limits it now falls back to a default time limit of 1000 ms and a default memory limit of 1024 MB.

These changes will go live in 2.16.0 which I am planning to release within the next few hours.

~I’ll wait until it’s done, unless that takes longer than expected (lets say 2 weeks) in which case I’ll publish a version using your regex.~

~I’m adding your regex to the UOJ parser, but I’ll wait with publishing it to give the admin some time to implement the feature, unless I have another feature to publish before that happens in which case your regex will be shipped with it (I hope to implement #74 next week).~

Nevermind, back to the original plan, I’m waiting until there is a more structured system for the time/memory limits because your regex only works on the initial html, not on the html after it has been formatted using MathJax.
