PE::Binary::get_content_from_virtual_address can now take either:

In the PE Python API:
* Merge 'PE.parse_from_raw' and 'PE.parse'
* Change 'PE.Binary.section_from_virtual_address' to 'PE.Binary.section_from_rva'
In the PE C++ API:
* Change 'Binary::section_from_virtual_address' to 'Binary::section_from_rva'
* Fix#25
* ELF `tiny` binaries are now handled (see #7)
* Computation of dynamic symbols can be done with differents methods:
hash table, sections and relocations. (See LIEF::ELF::DYNSYM_COUNT_METHODS)
