Attempt at fixing convert

[thomasrobiglio]

Hi all,
this is my attempt at addressing issue #327 and some other troubles I've found using the functions in the convert.py file.

Now it should be possible to:

1. Convert SC to Hyperg. and viceversa (using from_max_simplices and an analogous criterion when going from the other way around i.e. hyperdges -> maximal faces then i had all subfaces)
2. Convert from list, dict, and pd.DataFrame to Hypergraph as was possible before but without the issue of not returning anything. In this case if a pass an already existing Hypergraph instance then I have the in-place modification of the instance, else the function returns a new hypergraph()
3. Same as (2) for list, pd.Dataframe -> SimplicialComplex()

Hopefully this is what you had in mind when discussing #327 and this can be a useful contribution.
