Patch 4.0.0

[FulcrumOne]

perf:

• Improved library performance due to better task distribution between threads ([PERF] Improve library optimisation  #153)

fix:

• Fixed an issue with calling the library from non-main threads ([BUG] 3.0.0 crash in sheet View #147)
• Fixed an issue that made it impossible to interact with the app when the overlay was set to clear (How to implement the hideOverlay() function like 2.7.0. I didn't find the relevant API in 3.0.0 #150)
• Fixed a problem with the stacked popups background color
• Improved vertical popup animations

refactor:

• Renamed and changed some public API properties (see 3.x.x -> 4.0.0 Migration Guide for more information)
• Refactored several smaller files
