tja2fumen.py: Store additional metadata in song objects

Browse Source 
The original `readFumen()` function ignored storing information
that was irrelevant for writing osu files.

Now, however, we store this information for the purposes of
*writing* valid fumen files.

Although much of this information is probably irrelevant, doing so
ensures that we can get a 1:1 match between input and output,
which builds a solid foundation for converting TJAs to fumens.
