I tried to POST a file with `slug: %24%3A%2FStoryList` which is from `encodeURIComponent()`, but Response is `The name of new file POSTed may not contain : | or /`

When I `encodeURIComponent` it twice, then POST with `slug: %2524%253A%252FStoryList`, it Response with `PUT not supported on containers, use POST instead`

So what is the proper way to escape illegal characters in the filename?

I know why, POST in the NSS just call PUT to do the actual job:

```auto
async post (host, containerPath, stream, { container, slug, extension }) {
    await ldp.put(putUrl, stream, contentType)
}
...
async put (url, stream, contentType) {
    // PUT requests not supported on containers. Use POST instead
    if ((url.url || url).endsWith('/')) {
...
}

```

And PUT check whether slug ends with `/`

And this `/` is added here:
