Among the changes:
- It removes the ``and, or, not`` keywords
- It updates the Documentation
- It moves the internal structures in the ``details::`` namespace
PE's DATA_DIRECTORY_DEBUG does not define a single debug entry, but
a list of struct pe_debug entries (the number of entries is determined
by the data directory's size).
This commit reflect this layout by returning a vector<> when calling
PE.debug()
