Incorrect alignment in IMAGE_OPTIONAL_HEADER64 struct

[soheil-01]

Description

The current definition of the IMAGE_OPTIONAL_HEADER64 struct in the library has incorrect alignment specifications. Each field is currently aligned to 4 bytes (align(4)), which causes issues when reading PE NT headers using reader.readStruct().

Expected behavior

The IMAGE_OPTIONAL_HEADER64 struct should be defined without individual field alignemnts.
Here is a corrected version of the struct definition:
