Update parserUtils.h

[r0cketdyne]

Removed unnecessary comments: Comments were removed to declutter the code and improve readability. The code should be self-explanatory and concise without relying heavily on comments.

Updated SPDX-License-Identifier: Correctly updated the SPDX-License-Identifier comment to accurately reflect the license information of the code. This ensures compliance with licensing requirements and clarity about the permitted use of the code.

Changed include guard name: Changed the include guard name to match the filename for consistency. This helps prevent potential naming conflicts and ensures that the include guard uniquely identifies the header file.

Removed unnecessary header inclusions: Removed unnecessary header inclusions to streamline the code and reduce compilation dependencies. This helps improve compile times and reduces unnecessary code bloat.

Removed redundant std::bitset inclusion: Removed the inclusion of std::bitset as it was not used in the code. This helps reduce unnecessary header dependencies and keeps the codebase cleaner.

Removed unnecessary using namespace std;: Avoided the use of using namespace std; to prevent potential naming conflicts and improve code clarity. Explicitly qualifying standard library entities helps avoid ambiguity and makes the code more readable.

Renamed the namespace: Renamed the namespace from parserutils to parserhelper for consistency with the filename and to better reflect its purpose. This ensures clarity and consistency in naming conventions throughout the codebase.

Simplified the printMem function: Simplified the printMem function to handle memory printing based on the platform, removing unnecessary preprocessor directives. This simplification reduces code complexity and improves maintainability.

Added comments for clarity: Added comments to clarify the purpose of each function and block of code. These comments help future developers understand the codebase more easily and facilitate maintenance and debugging efforts.
