[FEATURE REQUEST] input_line, input_char, etc externals don't translate CRLF on Windows

[phated]

Describe the bug
If an input channel is in text mode, it is supposed to convert CRLF line endings to LF on Windows. I didn't test the output channels, but they are supposed to convert LF to CRLF on Windows (not sure if that is implemented).

If I read a line using input_line(), the string ends with \r on Windows.

Expected behavior
I expect the translation to happen as documented in the OCaml docs. I believe this would only be the case for Nodejs backend.

Versions
OCaml 4.12, js_of_ocaml 3.11.0 (but I checked the code and it hasn't been fixed with v4).

I looked into fixing this, but I think it'll take a lot of changes to the MlNodeFile implementation (read, read_one, etc).

There doesn't seem to be any support for automatic CRLF translation in nodejs.
The behavior can be emulated in mlNodeFd easily I think. Feel free to give it a go.
It should be easier now that stdin/stout are no longer special
