Loading C modules with pre-built wheels?

Hi lupa maintainers!

I'm currently trying to update a decade-old Python project ([chdkptp.py](https://github.com/a-hurst/chdkptp-python), a Python wrapper for controlling Canon cameras with CHDK firmware remotely over USB)  to work nicely on modern systems. chdkptp, the library that chdkptp.py is wrapping, consists of a C module and a bunch of Lua scripts.

To avoid needing to compile lupa from source (and work around the lack of older Lua versions on distros like Fedora, which only packages 5.4 whereas chdkptp needs 5.2 or 5.3), I was hoping to use the pre-built Lua binaries conveniently provided in recent releases of lupa. However, when I try to use them I get the following error:

```

```

After a bit of searching I found #247 which seems to have added a context manager to allow loading Lua with module support, but even after updating the lupa import code with the below I still get the same error:

```python
import lupa as lupa_main
with lupa_main.allow_lua_module_loading():
    import lupa.lua52 as lupa
```

Do the pre-compiled Lua versions in the Lupa wheels just not support dynamic libraries even with the recent fix, or am I doing something wrong? If the former, would it be possible to add dynamic library support to the pre-bundled wheels in a future release since it seems to be disabled by default anyway?

Thanks in advance!
