ot::Heap::String class
Represents a heap allocated string. The buffer to store the string is allocated from heap and is managed by the `Heap::String` class itself, e.g., it may be reused and/or freed and reallocated when the string is set. The `Heap::String` destructor will always free the allocated buffer.
