Refactor function parameters

[jxu]

At some point when we have an excessive number of parameters to functions I think it should be refactored, in particular mods (see bitwise enum https://github.com/ppy/osu-api/wiki)

https://github.com/llllllllll/slider/blob/master/slider/replay.py#L189-L392

What is the proposed alternative for this? Realistically, a Replay should be constructed from one of the smart constructors like from_path, which reads in a replay from a replay file on disk.

Using an enum that stores all the mods together

[tybug]

Circleguard has an implementation of this at https://github.com/circleguard/circlecore/blob/57465bb7d16cce9846de06fcb248a718b3bff7c4/circleguard/enums.py#L17-L251 (circleguard/circlecore#99), which seems a lot cleaner than passing every single mod.
