v0.4.4

Notable Changes

• Can use longer duration for certain pick notes, mostly used for bass notes, a bit trivial to create them in tabs, but the result sounds much nicer.
• Generate notes lane for guitar tab, which is really useful for learning fingerstyle or classical pieces.
• Use different fonts for note pitch/syllable, and fret number.
• Add command line args for choose language (e.g. add --lang zh-CN for Chinese version), no need for separate apps for language.
• Bugfix with layout mode logic for some corner cases.
• Some cleanup with Note struct.
