Title: Handle hex values for atom and residue numbers

It works as follows. It first tries to parse all values as decimal. If it fails on a value, it then tries to parse it as hex. If that succeeds, it sets a flag indicating that all further values should be parsed as hex.

This correctly interprets the values outputted by VMD, which is different from hybrid-36. Files using the latter will still load without problem, but there will be a gap in the atom IDs where it jumps from 99999 to A0000 (655360).
