Syntax error in reading a meshio.Mesh

Hi Marco, Thanks for supporting meshio imported meshes in vedo :) . In fact coincidentally I was trying to use vedo to render some of the meshes that I generated using pygmsh yesterday and stumbled across the above example. I think that the above lines would throw error with meshio-4.0.13. For instance

from vedo import show, Mesh
m2 = Mesh([mesh.points, mesh.cells['triangle']]) #this does throw an error
show(m2)

should be something like

import numpy as np
from vedo import show, Mesh
m2 = Mesh([mesh.points, np.vstack((
        cell.data for cell in mesh.cells if cell.type=="triangle"))
        ]) # this seems to render what I expect
show(m2)

and likewise. What do you think?

Hi Bhavesh, thanks a lot for spotting the issue and for the fixing.. I probably tested it on an old meshio version!
