fix terminal width

[tmzullinger]

0f81cd1 (Remove eyed3.utils.console.getTtySize() implementation (#682), 2025-10-22) didn't take into account the difference in the order of the tuple contents. As a result, it now returns the terminal height when it intends to return the width.

To demonstrate:

$ python -c 'print();
import shutil; from eyed3.utils.console import getTtySize;
print(shutil.get_terminal_size());
print(tuple(shutil.get_terminal_size()));
print(getTtySize())
'

os.terminal_size(columns=80, lines=24)
(80, 24)
(24, 80)

Fortunately, the output from shutil.get_terminal_size() is a named tuple. Use the os.terminal_size field names rather than slicing to get the terminal width in several locations. This makes the code clearer and less likely to accidentally transpose the height and width.

Fixes #689
