Support multiline squiggly

[EpicDima]

The problem is that ReplacementSpan does not support multiple lines, so the line cannot be wrapped by default. It is impossible to replace Span with another type, because we are drawing our own Path on Canvas.
The idea of the solution from the article https://medium.com/androiddevelopers/drawing-a-rounded-corner-background-on-text-5a610a95af5 and, accordingly, the code from https://github.com/googlearchive/android-text/tree/master/RoundedBackground-Kotlin.

I changed TextView to LeakCanaryTextView only in places where the text can now contain SquigglySpan.
