(2021-01-16) Implement osu!std pp changes

[KotRikD]

Hi! The PR is aimed at implementing the latest pp changes, I'm not a good C programmer, so I think there may be errors and improper formatting. Otherwise, tested on a couple of scores:

• the whitecat 1 089 pp play: picture comparing original osu tools and oppai ng
• non-funny play aimed at nf pp and hd perfomance: picture
• and non-funny bad scores with big count misses and low acc: picture
• mrekk's top 5 scores, whitecat's top 4 scores: (There will be no references, I tested through gosumemory with that calculations)

I'll merge when I have regenerated the test suite but it looks good so far

[KotRikD]

Be careful, I was trying to generate a test suite yesterday, some scores still hasn't been recalculated on bancho.

I tried manually generating the test suite, but something broke. probably error on my end. As far as i know, bancho recalc for the top ~20k players has finished.

for context:

Traceback (most recent call last):
  File "./download_suite.py", line 60, in <module>
    unique_maps = set([s['beatmap_id'] for m in [0, 1] for s in scores[m]])
TypeError: string indices must be integers

after running gentest.py

@MaxKruse https://ghostbin.co/paste/ah52d I fixed this mistake here, try it!

But as I said before, some scores still not recalculated just comapre this

[MaxKruse]

PP Recalc is done, packing is possible. Pre-packed: https://lithibae.s-ul.eu/8D5oqmLT

can confirm that 2153557 is still not recalculated as @KotRikD said, need to figure out how to generate a good enough test suite for now that doesn't include old scores

[Francesco149]

even if i pick pretty new maps there's still many scores that aren't recalced hmmm

[Francesco149]

if I include only the current top 10 or so's top plays the tests pass, let's use that as the temporary test suite
