This commit changes the semantics of `CurrentFrame` and `NextFrame` of the class.
The ordering of `NextFrame.Time` and `CurrentFrame.Time` was dependent on the current direction.
Now, it should always satisfy `CurrentFrame.Time <= CurrentTime <= NextFrame.Time` except at the start/end.
This change, however, doesn't break existing deriving classes if the template code pattern usage of interpolation is used.
The deriving class code can be simplified due to the elimination of nullable types. I didn't include those changes in this commit.
I removed `StreamingFramedReplayInputHandlerTest` for now, as it is almost-duplicate of `FramedReplayInputHandlerTest`. I'll include more tests in later commits.
This commit fixes#6150.
- Removed the Xamarin.Essentials package from osu.Game and added it to osu.iOS and osu.Android only.
- iOS and Android implementations use Xamarin.Essentials.Battery, while the Desktop implementation
only returns 100% battery for now.
- Added a BatteryCutoff property to PowerStatus so it can be different for each platform (default 20%, 25% on iOS)
- Uses Xamarin.Essentials in osu.Game.PlayerLoader to check battery level
- Encapsulated battery checking in the public BatteryManager class so battery level and plugged in status can be accessed and edited in TestPlayerLoader
- When checking battery level, catch NotImplementedException thrown by Xamarin.Essentials.Battery on non-mobile platforms
- Added visual unit tests for battery notification
To mock battery status and level, we had to define a batteryManager object in TestPlayerLoader and add a new function ResetPlayerWithBattery()
