This is a simple Python-based implementation of the classic game where you play against the computer. The game includes features like scorekeeping and multiple rounds.

- Play multiple rounds against the computer.

- Keep track of the score for both the user and the computer.

- Input validation to ensure only valid choices are accepted.

- Display the final result at the end of the game.

When you run the script, you'll be prompted to enter the number of rounds you wish to play.

For each round, you will be asked to choose one of the following options: `rock`, `paper`, or `scissors`.

The computer will randomly select its choice.

The winner of each round is determined based on the classic rules of Rock, Paper, Scissors:

- **Rock** crushes **Scissors**

- **Scissors** cuts **Paper**

- **Paper** covers **Rock**

After each round, the scores will be updated and displayed.

At the end of all rounds, the final scores will be displayed, and the winner will be announced.

Welcome to Rock, Paper, Scissors!

How many rounds would you like to play? 3

Enter rock, paper, or scissors: rock

Computer chose: paper

Computer wins this round!

Scores => You: 0 | Computer: 1

...

Congratulations! You won the game with a score of 2 to 1.
