Reusable mesh geometries

[ThaiLe-gt]

Hello Kovacsv!!!

Thank you for your great library!!!
I used your library in Node JS successfully.
But I have faced some issues:

• The STP files which over >50MB can not display in Three js (Please check my file attached below).
• The mesh geometries that have the same properties are not reusable in the result, which will affect the performance for loading and importing.

Just to pitch in, this seems to be choking the function occt.ReadStepFile( fileBuffer ) since the fileBuffer appears to be an array of 73+ million in length.

I think it would be also solved by #5. The basic problem here is that the built-in triangulation logic can end up with really large meshes, so it would be great to make users able to define the quality from the outside.

Triangulation parameters are available in version 0.0.14.
