i've decided it is Minor, cuz I've added backwards compatible functionality to the public API (ConvertTimeout which is not required)
See https://semver.org/spec/v2.0.0.html#spec-item-7

this is not as I could imagine best, but it works.
I've tried to do it by calling
proc.WaitForExit(milliseconds: timeeout)
but this requires that output of process is asynchronous.
I've tried to do it also by implementing events:
proc.OutputDataReceived += (sender, outputLine) => ...
proc.ErrorDataReceived += (sender, errorLine) => ...
but I failed to convert outputLine.Data to bytes[]. Thats cuz it is String, not Stream (as in proc.StandardOutput.BaseStream).
I've tried provide some encoding to process output and convert it, but any way I tried to do it, the resulted PDF was broken.
Finally I gave up and it that way
