StringBuilderPool
StringBuilderPool is a utility class found in various programming environments, particularly in .NET, designed to manage and reuse instances of the StringBuilder class. The primary purpose of StringBuilderPool is to optimize performance by reducing the overhead associated with creating and garbage collecting StringBuilder objects. When a StringBuilder is needed, the pool can provide an existing instance instead of allocating a new one. Similarly, when a StringBuilder is no longer required, it can be returned to the pool for future use.
This pooling mechanism is beneficial in scenarios where StringBuilders are frequently created and discarded, such as
Usage typically involves a `Rent` method to obtain a StringBuilder and a `Return` method to release it
