Feature Request: Custom Ratios Bar

[tonykam-zlashy]

Hi~ The new feature of this library is fantastic! However, it would be great to have a custom ratio bar that allows for a custom list of ratios, rather than just adding ratios alongside predefined options. For my use case, I want to restrict users to select only the 1:1 ratio to maintain image readability. This added flexibility could significantly enhance the user experience. Thank you for considering this!

From this example, I want to allow users to crop image with "My Custom Ratio" only.

I will implement it in the upcoming version
