Function inRange

inRange(x: number, min?: number, max?: number): x is number
Checks if a number x is within a given range (inclusive). This function also serves as a type guard, narrowing the type to number.

At least one of min or max must be provided. If min happens to be larger than max, it swaps them and works gracefully.
Parameters
- x: number
  The number to check.
- Optionalmin: number
  The minimum value of the range (inclusive). If undefined, only the max is checked.
- Optionalmax: number
  The maximum value of the range (inclusive). If undefined, only the min is checked.
Returns x is number
true if x is within the specified range, false otherwise.
Throws
if x is not a number.

Throws
if either min or max are defined, but are not numbers.

Throws
if neither min nor max are provided.
Example
```
inRange(5, 0, 10) => true
inRange(5, 5, 10) => true
inRange(5, 0, 5) => true
inRange(5, 4) => true
inRange(5, 6) => false // 5 >= 6
inRange(5, 10, 2) => true
inRange(5, undefined, 4) => false // 5 <= 4
```
