Taiko length bonus fix by calculating consistency for each skill

[TheDark98]

The change modifies:

For all gamemode:

• New value, ConsistencyFactor, new variable to calculate the consistency of the map, represented by a value from 0 to 1, where 1 represents the highest consistency possible in a map and 0 the lowest consistency possible in a map..

For taiko only:

• ConsistencyFactor for each skill.
• New length bonus formula calculated with ConsistencyFactor for each skill + total.
• Length bonus affect star rating.

Overall, can we have some documentation surrounding how this works? Whilst I am familiar with the general concept by reading the code, maybe some notable values changes etc? Also, you'll need to fix commit history.

Sorry I didn't see it before. I've also prepared documentation for my concept.

why is this a global difficulty attribute ?

[TheDark98]

I want to add this to each game mode, so I need it to be global.

It doesn't need to be global, as this is directly targeting the taiko ruleset.
