• from png: open png files in terminal
• to png: converts ansi outputs colored texts, tables, etc into image file

do you happen to know why this file is changing all of a sudden? 🤔

I added a null check where (I think) was the cause of the issue and from the output it most likely is

EvalBlockWithInput(Span { start: 107690, end: 107694 }, [CantFindColumn { col_name: "plugin", span: Span { start: 114641, end: 114647 }, src_span: Span { start: 114634, end: 114640 } }])

I'm fine with landing this but I think all those eprintln messages should be put behind a --verbose flag.
