Repository: tldr-pages/tldr-python-client

Issue:
`tldr --list` ingnores language-specific cache directories
The problem is on this line:

https://github.com/tldr-pages/tldr-python-client/blob/68acf0531668f3a248127bd4e25140ed420ceff9/tldr.py#L315

I think that if a language is explicitly set, tldr should use its cache directory.

For example:

```
# LANG=zh_CN tldr lspci
…
# LANG=cs_CZ tldr cd
…
# ls -la /root/.cache/tldr/
total 0
drwxr-xr-x. 4 root root 56 Mar  4 12:30 .
drwxr-xr-x. 3 root root 48 Mar  4 12:25 ..
drwxr-xr-x. 3 root root 36 Mar  4 12:30 pages.cs
drwxr-xr-x. 3 root root 34 Mar  4 12:25 pages.zh

# LANG=zh_CN tldr --list
[]
# LANG=cs_CZ tldr --list
[]
```

I'm using the latest release.
