This pull request adds two new standalone RxJS operators, tapOnce and tapOnceOnFirstTruthy, to the utility library. These operators allow for conditional execution of functions based on emitted values.
tapOnce: Executes the provided function only once when the value at the specified index is emitted.
tapOnceOnFirstTruthy: Executes the provided function only once when the first truthy value is emitted.
What are your thoughts on these operators? They seem particularly useful for scenarios where you need to initialize something, such as a modal element, as soon as the first value from a source is emitted.
This is my first PR on GitHub, so I appreciate your patience :)! Any contributions, feedback, or change requests are more than welcome.
