Issue #91: Add support for ImageButton

[t-regbs]

I added this check to the LineWriter:

fun startLine(text: String = "") {
        if (builder.isNotEmpty() && checkLast('(').not()) {
            repeat(indent) { builder.append(INDENT) }
        }
        builder.append(text)
}

Where checkLast is

fun checkLast(char: Char): Boolean {
        return builder.last() == char
}

Because without the check instead of having as desired:

Button(onClick = {}, modifier = Modifier.width(100.dp).height(100.dp)) {
         Image(imageResource(R.drawable.ic_lock_power_off))
}

I get:

Button(onClick = {}, modifier = Modifier.width(100.dp).height(100.dp)) {
         Image(      imageResource(R.drawable.ic_lock_power_off))
}

Hey @t-regbs. Thank you for your pull request. Overall this looks good. I wonder if we can solve the problem you are describing differently than the change in startLine(). The function startLine() is supposed to start an indented line and now you made it more complex handling other unrelated cases. So, I wonder if we should avoid calling startLine() in the first place if this is not what we want here... but I haven't looked closely at the code yet.
