dxfReaderAscii:readInt64() never reads a 64 bit

[PaulFocus]

The mentioned method seems bugged:

libdxfrw/src/intern/dxfreader.cpp

Line 251 in 34b65b0

bool dxfReaderAscii::readInt64() {

The member dxfReader::type is set before call to readInt16(), which overwrites dxfReader::type. Therefore enum member INT64 will never be used, thus the member dxfReader::int64 has no use.

EDIT: Are codes 160 to 169, which require reading 64 bit integers, even used or supported by the ASCII DXF format?
