Windows: coroutines should display a message that they don't work on Windows, instead of complaining about photonwrapper.so not found

[archyboy]

Describe the bug

\v/thirdparty/photon/photonwrapper.so' not found

Reproduction Steps

module worker

import os
import net
import time
import coroutines


pub struct Worker{
pub mut:
	id   int
	hash string
	name string
}

pub fn (m Worker) start() {
	print('Starting working process from ${m.name}')

	for i in 0 .. 10+1 {
		println('${m.name} is running ${i} times')
		coroutines.sleep(2 * time.second)
	}
}

Expected Behavior

looping trough []workers Worker array executing type method run() as coroutines

Current Behavior

tcc: error: file 'C:\Users\Archy\Devel\v/thirdparty/photon/photonwrapper.so' not found
...
==================
(Use `v -cg` to print the entire error message)

Coroutines are in very early WIP status. They don't work on Windows at all (the photon lib doesn't have a Windows version, though they are supposedly working on it).

Even on Linux/Mac, they are... touchy.

So this isn't actually a bug, just an unimplemented feature for Windows.

That said, the example should probably tell you that if you try to compile it on Windows.
