Lerps

Has some lerp functions that look like this:

/**
 * Given a startValue and endValue, returns a function that,
 * when passed an alpha value, returns an interpolated value between the two.
 */
type LerpFunction<T> = (startValue: T, endValue: T) => (alpha: number) => T;

These are the types:

string
number
boolean
Region3
CFrame
UDim2
UDim
Ray
Rect
Color3
Vector2
Vector3
NumberRange
ColorSequence
NumberSequence
PhysicalProperties
NumberSequenceKeypoint

The string lerp function is only for Lighting's TimeOfDay property, although probably shouldn't be.
