fix non-working loop when lowerLimit equals 0

[yutro]

Summary

Problem

Loop stuck on upperLimit when loop:true and lowerLimit presented but equals 0, expected behavior that it will go to lower limit when it's presented.
I believe it's a bug 🤔

• Loop stuck on upperLimit when loop:true but no lower limit presented
  I think it would be nice if we could extend it to go to start (initial ) value if loop:true but lower limit not presented

you can test those cases here (wanted to record some gifs but something wrong with my gif recorder 😞 )

Solution

what was done in this PR:

• fix non-working loop when lowerLimit equals 0
• when loop:true and lowerLimit not presented, loop goes to start (initial) value after reaching upperLimit value

let me know WDYT about it 😄

P.S I'm a big fan of this library and always wanted to made something for it 😄 looks like it's my chance 😄
