Unable to load sharded data from files without filetype extensions

I am trying to load data from directory of jsonlines formatted files which lack the .json extension.

I have tried:

```
data('/path/to/dir/')
data('/path/to/dir/*')
data(JSONLines('/path/to/dir/'))
data(JSONLines('/path/to/dir/*'))
data(Directory(JSONLines)('/path/to/dir/'))
data(Directory(JSONLines)('/path/to/dir/*'))
```
all of which throw either ` Unable to parse uri to data resource` or `No such file or directory`.

I am able to parse a single file with:

```
data(JSONLines('/path/to/dir/file1'))
```

Is this a bug / unimplemented functionality or am I doing something wrong?
