COMP: Remove clrLine in itkExtras

A special escape character was used in python to display the loading process.
This was intended to display the loading sequence on one line in the terminal.

When there are errors in the python tests, the error messages are cluttered with : [2000D[NON-XML-CHAR-0x1B] in Cdash
Anyway this hack also seems not to work  on OS X's terminal.
I suppose we don't want to support all types of terminal types and configurations here.

BUG: Windows BigTIFF errors: stat failure and lack of COMPRESSION_DEFLATE

Two bug fixes in itkTIFFImageIO.cxx:
1. On attempting to open a BigTIFF file 'stat' gave an error, because on Windows _stat64
must be used in this case.  The fix was to check for the OS, and if WIN32 use _stat64
in addition to stat.
2. The function TIFFReaderInternal::CanRead() was missing a line for COMPRESSION_DEFLATE.
This enables the formerally patented GIF compression, but the patent expired in 2006.
