to_rdkit_mol should have no_implicit option

[richardzhu]

If we are maintaining a tinygraph obj that keeps track of hydrogens using the explicit_h prop, then if we export to RDKit mol using to_rdkit_mol we should also also set no_implicit on the atoms that have it, right? I was thinking something like

if explicit_h_prop is not None:
    atom.SetNumExplicitHs(int(g.v[explicit_h_prop][i]))
    atom.SetNoImplicit(True)

Line 116 in f163816

if explicit_h_prop is not None:

Richard this seems like a good idea, would you be willing to write a patch, a test and create a PR ? :) If you create the PR I think our CI system should test it for you and then we'll have @WilliamsJakeL look at it and merge?
