parsetja.py: Add applyFumenStructureToParsedTJA function
...
This function basically just takes the output of the `getCourse`
function, and restructures it so that it more closely matches the
structure of the fumen `song` format.

tja2fumen.py: Fix assumption about drumroll padding bytes

The 8 bytes after a drumroll are NOT just padding, as
`fumen2osu.py` assumed. There is some kind of metadata here;
I just need to determine what it stands for.

tja2fumen.py: Rewrite song information to fumen files
...
On at least one song I've tested, this creates a perfect match,
meaning that we now have the ability to create a fumen file
from a "song" object.
The next challenge is reading TJA files into "song" objects.

tja2fumen.py: Store additional metadata in song objects
...
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.

tja2fumen.py: Read the "unknown" part of the header

This seems to contain metadata that was ignored by the
original `readFumen()` function. I'm curious to explore
what these values represent, and how they vary from
fumen to fumen.

tja2fumen.py: Differentiate between note types
...
Having multiple note values map to identical strings
(e.g. "Don", "Ka", "DON", "KA") caused issues when
writing these strings back to .fumen files.
So, we make sure that each note type has a unique
string associated with it.
