Arguments passed to `run_plugin` replace backslash with forward slash

[matham]

I was using BigStitcher from pyimagej on Windows and needed to pass in paths. But, BigStitcher would choke on the paths claiming it can't find files there.

I traced down the issue to pyimagej automatically replacing backslashes with a forward slash. When I removed this, BigStitcher finally worked.

pyimagej/src/imagej/__init__.py

Line 712 in 17fdca8

temp_value = str(value).replace("\\", "/")

Should this replacement be optional, perhaps guarded behind a switch, like ij1_style!? I ended up replicating the format code and passing in args as a string, without this replacement.
