Function isNonEmptyString

isNonEmptyString<T>(value: T, trim?: boolean): boolean
Determines whether the given value is a non-empty string.

This function first checks if the input is a string using isString. If it is not a string, the function returns false. If it is a string, it then checks whether the string contains any non-empty content.

By default, the function trims the string before checking its length, which means strings containing only whitespace (e.g., " ") will be considered empty. This behavior can be controlled using the trim parameter.
Type Parameters
- T
  The type of the value being checked.
Parameters
- value: T
  The value to validate as a non-empty string.
- trim: boolean = true
  Whether to trim whitespace from the string before checking its length. Defaults to true.
Returns boolean
- A boolean indicating whether the input is a non-empty string.
Example
```
isNonEmptyString('hello'); // true
isNonEmptyString('   '); // false (trim is true by default)
isNonEmptyString('   ', false); // true (whitespace is counted)
isNonEmptyString(123); // false
isNonEmptyString(null); // false
```
