Some suggestions for optimizing edge_tts

[Tspm1eca]

edge_tts_provider.py

• Using the lameenc library to improve speed and correct sound quality (currently: 33kbps, but should be: 48kbps).

epub_book_parser.py

• Using book.spine to ensure the output order is correct.
• Fixing decimal point issue (current problem: 6.3km => 6.km).

Suggestions

• Remove URLs from the text, such as https://example.com (hearing these in mp3s can be quite annoying).

Actually, I have already made modifications myself, but I changed quite a lot (and mainly focused on the Chinese book). I'm not sure if everyone will accept these changes, which is why I am bringing up the issue here.

Here are my modifications :
