xyz file produced by LAMMPS cannot be parsed

[mfherbst]

Hi @jameskermode. In AtomsIO I received mfherbst/AtomsIO.jl#19, which essentially is a parsing failure in ExtXYZ for an xyz file produced by LAMMPS --- so something I'd argue we would want to support.

Here is a simplified reproducer:

where the error message printed is:

Failed to parse string at pos 7

I would also use this feature. If it's something easy to change I can make the PR.

Thanks for the reminder @ejmeitz. I implemented most of what is needed in libAtoms/extxyz#16 but need to make a new release of libextxyz and then update ExtXYZ.jl to use it. What is blocking this at the moment is the failures to build on Windows in libAtoms/extxyz#17, so if you have the time or expertise to help with that this would be much appreciated.
