Support Jump Indicators on OAT View

[alonalbert]

Notes:

• DexTextArea & OatTextArea are trivial, but I think it results in a cleaner project.
• The oat package currently contains only OatTextArea, but it would make sense to move the oat parsing there too.

Yeah, we should have something like:

sealed CodetextViewContent {
    class CodeContent(classes: List<CodeClass>): CodetextViewContent
    class ErrorContent(error: String) : CodetextViewContent
}

Can you share an example of a OAT jump that needs to be computed?

I'm not sure I understand.
