Check whether `a` is fuzzily less than `b`.

`a` is fuzzily less than `b` if it is less than `b + epsilon`.

@function Phaser.Math.Fuzzy.LessThan
@since 3.0.0

@param {number} a - The first value.
@param {number} b - The second value.
@param {number} [epsilon=0.0001] - The epsilon.

@return {boolean} `true` if `a` is fuzzily less than `b`, otherwise `false`.
