ASCII STL to 3MF conversion fails

[vijaiaeroastro]

I tried reading a simple ASCII stl file with Converter.cpp example
The geometry is just a simple box. The example fails with the following error

------------------------------------------------------------------
3MF Model Converter
lib3mf version = 2.2.0
------------------------------------------------------------------
reading /home/vijai/Documents/Geometries/stl_box_ascii.stl...
Lib3MF Error 5 (Reading from a stream was not possible)

Binary version of same file works. I have attached the ascii stl here.
I am not sure if lib3mf is only designed to read binary STL's. In that case, just let me know and I will close the issue.

It's a missing feature... the current implementation only reads binary STL:

lib3mf/Source/Common/MeshImport/NMR_MeshImporter_STL.cpp

Line 132 in 30d5c2e

pStream->readIntoBuffer(&aSTLHeader[0], 80, true);

It would be nice to also have ASCII-reading, yes.

Include the ASCII stl reader from #364 into lib3mf.
