/**
* Clamps a number to a specified range.
* @param value The number to clamp.
* @param range The range to clamp to, as a tuple of min and max values.
* @param options Optional parameters.
* @param options.inclusive Whether the clamping should be inclusive of the min and/or max value.
* - If `true`, the clamping is inclusive of both min and max.
* - If `false`, the clamping is exclusive of both min and max.
* - If `'min'`, the clamping is inclusive of the min value but exclusive of the max value.
* - If `'max'`, the clamping is exclusive of the min value but inclusive of the max value.
* @returns The clamped number.
* @example
* ```typescript
* clamp(3, [1, 5]); // 3
* clamp(5, [1, 5]); // 5
* clamp(5, [1, 5], { inclusive: false }); // 4
* clamp(1, [1, 5], { inclusive: 'max' }); // 5
* ```
