Damien George ecdf6cdc5b tools: Fix up pybcdc.inf generation: new lines and hex digits.
Using Python's file open in 'r' mode opens it for text reading, which
converts all new lines to \n.  Could use 'rb' binary mode, but then
don't have access to the string Template replacement functions.  Thus,
force the output to have '\\r\\n' ending.

Also fix regex to match hex digits.
