• Description: Simple structure and functions to read and write PDB files
• Release notes:

## Breaking changes:

- The `element` field of the `Atom` structure is now called `pdb_element`. If `element(::Atom)` is called, the value of the `pdb_element` field will be retrieved if not empty and not `"X"`. 
- The `atomic_number(::String)` was removed, as it was type-piracy because the function was defined in `AtomsBase`. Use `atomic_number(Atom(name="NT3"))` instead. 

## New features

- `select_with_vmd` supports a `AbstractVector{<:PDBTools.Atom}` as input. It will write a temporary PDB file and run VMD.
- `pdb_element` and `charge` are now exported.
