In NimScript mode, make `commandLineParams()` more useful

[Jinwoo Lee]

Summary

cmdline/commandLineParams() (and the parseopt module) is not very friendly with NimScript mode

Description

Currently, when nim is invoked in script mode, cmdline.commandLineParams() returns all the parameters including the flags/arguments that are passed to the nim compiler. For example, with this script (say test.nims):

#!/usr/bin/env -S nim e --hints:off

import std/cmdline

echo "params: ", commandLineParams()

invoking the script via $ ./test.nims foo bar outputs

params: @["e", "--hints:off", "./test.nims", "foo", "bar"]

Ideally I hope it only returns @["foo", "bar"], ignoring the first 3 parameters.

This is annoying because the script needs to ignore the first three parameters to parse correctly. It's more annoying because the number of parameters to ignore depends on what flags/arguments that I pass to nim.

And this makes it very difficult to use the same code both in script mode and in compile mode.

Can it be made so that the script mode strips out the parameters that are passed to nim
