Function integrate

integrate(
    f: (x: number) => number,
    lower: number,
    upper: number,
    options?: IntegrateOptions,
): IntegrateResult
Integral of a function of one variable over a finite or infinite range. Equivalent to R's integrate().
Parameters
- f: (x: number) => number
- lower: number
- upper: number
- options: IntegrateOptions = {}
Returns IntegrateResult
Example
```
integrate((x) => Math.exp(-x * x / 2), -Infinity, Infinity).value; // 2.506628274115034 (sqrt(2 pi) = 2.5066282746310002)
```
