Add DWG uploader

Hi @mfranzon
Would it be better to use an external API to convert DWG files into DXF and that would be the easiest option.
Or to use a library like libredwg-web to convert DWG into a database format and then feed it into our existing loadDxfFile function (though this might require rebuilding the WASM module with DXF writing enabled)?
A third option would be to use the same liberary to parse DWG, extract the entities, and then generate DXF text ourselves from the extracted data before passing it to loadDxfFile.

@pcolt How do you think we could solve this one?

Hey! My plan would be having a routine like loadDwg alongside the loadDxf, not necessarily convert a dwg in dxf. What do you think?

@mfranzon If you can give me some uses cases of why do we need to upload the DWG or DXF (or other formats) so i can better understand what's in your mind.
If it’s only for rendering the 2D part, then we don’t really need the extra details that DWG provides.
I could create a simple DWG parser alongside the DXF that extracts the important entities as you said.
