Generated python code initializes static variables in the wrong order

**Environment**
macos monterey 12.1
haxe 4.2.4
utest 1.13.2
haxe-concurrent 3.0.2

The issue can be reproduced by creating a test case like the following one (even if the issue is triggered by the interaction between the libraries `utest` and `haxe-concurrent`, I don’t think that it is caused by them as I’m explaining below)

```
package foo;

import utest.Assert;

class TestCase extends utest.Test {
static var ex = hx.concurrent.executor.Executor.create();

function testFoo() {
Assert.pass();
}
}
```

The reported error is

```
Traceback (most recent call last):
File "/Users/foo/temp/bin/python/main.py", line 6819, in

```

The last part of the generated python file is this

```
foo_TestCase.ex = hx_concurrent_executor_Executor.create()
hx_concurrent_ConcurrentException.INDENT = " "
hx_concurrent_executor_ScheduleTools.HOUR_IN_MS = 3600000
hx_concurrent_executor_ScheduleTools.DAY_IN_MS = 86400000
hx_concurrent_executor_ScheduleTools.WEEK_IN_MS = 604800000
hx_concurrent_lock_RLock.isSupported = True
python_Lib.lineEnd = ("\r\n" if ((Sys.systemName() == "Windows")) else "\n")
utest_TestHandler.POLLING_TIME = 10
utest_AccessoryName.SETUP_NAME = "setup"
utest_AccessoryName.SETUP_CLASS_NAME = "setupClass"
utest_AccessoryName.TEARDOWN_NAME = "teardown"
utest_AccessoryName.TEARDOWN_CLASS_NAME = "teardownClass"

foo_TestAll.main()
sys_thread__Thread_Thread_Impl_.processEvents()
```

As you can see the problem is that the executor `hx_concurrent_executor_Executor`, which internally uses `python_Lib.lineEnd` for logging, is created before the variable `lineEnd` is assigned.
