Cannot copy nested directory starting with underscore prefix

[Maluscat]

Version: Lume v1.19.4
OS: Arch Linux

site.copy fails when trying to copy a directory hierarchy starting with an underscored folder:

site.copy('_lib/someLibrary/css/', 'lib');

All files inside _lib/someLibrary/css/ should get copied over into the _site/lib/ folder. Instead, no files will get copied over whatsoever.

When the initial folder is not prefixed with an underscore, the sites are copied over as expected (but then, potential page files like .md or .html will get rendered, which is not the desired behavior).

As is written in the docs, copying a single underscored folder works just fine, for example:

site.copy('_static', '.'); // Works as expected

When Lume traverses the source folder and find a folder that must be ignored (like those starting with an underscore), doesn't enter in this folder.
But you have a fair use case. I'll fix it. Thanks
