Windows does not identify folders correctly in zip

I'm trying to extract https://github.com/HaxeFoundation/haxe/releases/download/3.2.1/haxe-3.2.1-win.zip using decompress 4.0.0, but get a whole bunch of errors like

```
Error: EISDIR: illegal operation on a directory, open '...\haxe-3.2.1\std\flash\geom'
at Error (native)
errno: -4068,
code: 'EISDIR',
syscall: 'open',
path: '...\haxe-3.2.1\std\flash\geom'
```

from file entries like

```
{ mode: 420,
mtime: 2015-10-11T11:00:44.000Z,
path: 'haxe-3.2.1/std/flash/geom/',
type: 'file',
data: }
```

It looks like the directories in that archive are marked as type: file (instead of directory), but oddly enough it only happens for that particular archive.

A quick fix I found was to treat files as directories if their path ends with a '/' (i.e. `if (x.type === 'directory' || x.path.endsWith('/')) { /* mkdir -p */ }`), but I don't know if that's a good idea or not.

Reproduce the extraction with the linked Haxe Windows ZIP and inspect how entries with paths ending in '/' are classified and written. Done means those entries are treated as directories and the archive extracts without EISDIR errors; no specific source file or test is named in the issue.
