lib: support min/max values in validateInteger()

Browse Source 
This commit updates validateInteger() in two ways:

- Number.isInteger() is used instead of Number.isSafeInteger().
  This ensures that all integer values are supported.
- Minimum and maximum values are supported. They default to
  the min and max safe integer values, but can be customized.
