Enhance Writer class with GetEndianness, improve type safety, and in-memory swaps

[lammmab]

Introduces several improvements and fixes focused on code safety, maintainability, and API flexibility.

Changes

Build System and Code Safety Enhancements:

• Added strict compiler warning flags for both MSVC and non-MSVC compilers in CMakeLists.txt to enforce higher code quality and catch more potential issues at compile time. These flags are applied to all main targets (processing, interface, esfa). [1] [2] [3]

API Improvements and Flexibility:

• Added overloaded ParseAsset and ExportAsset methods to the Processor class, allowing direct parsing from and exporting to arbitrary streams, not just files. This increases flexibility for asset handling. [1] [2] [3] [4]

Type Safety and Consistency:

• Updated the BitConverter methods to use size_t for offsets instead of int32_t, and replaced C-style casts with static_cast for improved type safety and clarity. Also made the floating-point conversion static assertions more accurate.
• Updated Reader methods to use static_cast and reinterpret_cast for type conversions, and ensured consistent use of buffer sizes and types, reducing the risk of undefined behavior. [1] [2] [3] [4] [5] [6]

Minor Refactoring and Cleanups:

• Added default initialization and constructors to AssetMeta for safer and more convenient usage.
• Removed an unused member variable from FileStream for code cleanliness.
• Added a GetEndianness method to Writer for symmetry with Reader.
