Subject: [PATCH] Update IERC20.cairo

This pull request introduces optimization improvements and comprehensive documentation for the Cairo implementations of the IERC20 interface and an access control mechanism. The aim is to enhance readability, maintainability, and provide clear guidance on the purpose and usage of each function within the contracts.

Changes:
IERC20 Cairo Contract Enhancements:

Added concise English comments to explain the functionality and purpose of each function within the IERC20 interface. This includes descriptions for name, symbol, decimals, totalSupply, balanceOf, allowance, transfer, transferFrom, and approve functions.
Optimized function stubs for better understanding and future implementation ease.
Access Control Cairo Contract Improvements:

Implemented an access control mechanism with a focus on a permitted minter pattern. The contract ensures that only an authorized minter can perform specific actions.
Added detailed comments to elucidate the workings of the constructor, getter, and internal functions that enforce the permitted minter only access.
Documentation:
Every function now includes documentation comments that describe its action, parameters, and return values. This aims to aid developers in understanding the contract's capabilities and restrictions without diving into the code details.
Purpose:
The enhancements are designed to make the contracts more accessible to contributors and developers. By improving documentation and optimizing the code structure, we aim to foster a clearer understanding and facilitate easier modifications and extensions in the future.
