PP values between /json and /api/calculate/pp endpoint are different.

1. The pp values shown in the /json endpoint are different than the values when an equivalent calculation is done in the /api/calculate/pp endpoint. I believe this is due to /json using the lazer calculator and /api/calculate/pp being dependent on Rosu which has not been updated for the recent rework.

Steps to recreate:

• Leave osu! stable open on a map and hit the /json endpoint
• On the same map, hit /api/calculate/pp?lazer=false
• The "pp" key on the /api/calculate/pp?lazer=false endpoint will have a different value than the "pp": "100" key on the /json endpoint

We are using patched version of lazer for pp calculation. See upstream issues below.

pp values returned by /json is correct. /api/calculate/pp is incorrect. It's still using rosu because the json is created by rosu.

Is porting /api/calculate/pp over to the lazer calculator within scope? Seems confusing to have two different methods of doing the same thing, especially if one of them pulls in an external dependency that isn't officially maintained.

Yes it is planned to be replaced eventually.
