Add type annotations to ada-unicode.py, just enough to make pyright
happy:
$ pyright --version
pyright 1.1.359
$ pyright ada-unicode.py
0 errors, 0 warnings, 0 informations
Introduce a `Range` class instead of using separate variables and
tuples, to make the code and type annotations a bit cleaner.
When running ada-unicode.py, I get a diff for ada-casefold.h, but I get
the same diff before and after this patch, so that is a separate issue.

This trailing comma seems weird.

Thanks, will push.

When it decides to put the arguments one per like, black adds that
trailing comma. I guess it avoids having a diff on this line should you
add another argument after that.
You can also add the trailing comma yourself to force black to put
things one per line:
foo = (1, 2, 3)
bar = (
1,
2,
3,
)
print("foo")
print(
"foo",
)
It sometimes makes things more readable (not in the dummy examples
above, but in real life code).
