Matt a03e4b9413 fix: budget the work 3MF and DXF import does, not only its output ...

3MF: flatten budgeted triangles but copied the whole vertex array for every
placement, so an object with 100,000 vertices and one triangle placed by 500
build items reached 6.8 GB resident, and 10,000 items (still a ~200 KB file)
asked for about 140 GB and aborted on the allocation. Copy only the vertices
the triangles reach, keeping their relative order so an ordinary mesh is
numbered as it was in the file.

DXF: every bound in convert was on the geometry that comes out, and a block
that emits none tripped none of them. Six self-inserts in one empty block fan
out to 6^16 visits, and a 176-byte file never returned. Count entities visited
and array cells placed against a work budget, skip the array loop for a block
with no geometry, and bound the array size on its own.

Fixes #144
