[Major] Spotifydl: v1.0.0

• Now supports artist downloading 🥳 HUGE thanks to @phyzical (Jack) for his contribution.
• Source rewrite and dependencies
• Better caching support
• Much faster downloading
• Skips too lengthy songs. (Eg. some songs on youtube are not uploaded so something else gets downloaded such as some biography movie of 1hour+ duration, which is now fixed)
• Code dryup and refactoring.

All the updated are done by @phyzical ❤️ And his work is greatly appreciated :) Thank you for contributing.
