fix: lambdas and parens, multiple indents

[ludamad]

Closes #346

Background: Thanks for making this tool. Lambda bugs were getting in the way in some cases, and I'd like to adopt it.
It seems INDENT and DEDENT were not emitted inside a lambda, other than one level deep.
I dove in and tried to fix it. The big test suite was a help as I thought I was done a few times.

I still noticed edge-cases with lambda, but mostly stuff like

var a = {
   f = func():  for x in y: print("hey")
}

which I looked at and had some ideas, like generating a virtual newline, but am leaving it here as I can work the codebase into shape now within the edge-cases

opinionated, but I think fixing compound func stmt is the way to go and this works some of the time. could def revert this part tho
