Load of VALD linelist file fails with PluginNotFound from pybtex

[andreok]

Hello,

I am trying to execute pySME on Google colab, but the load of the sample VALD linelist file for the Sun fails with the following error:
".../lib/python3.10/site-packages/pybtex/plugin/init.py in _load_entry_point(group, name, use_aliases)
79 for entry_point in pkg_resources.iter_entry_points(search_group, name):
80 return entry_point.load()
---> 81 raise PluginNotFound(group, name)
82
83

PluginNotFound: plugin pybtex.database.input.suffixes for suffix .bib not found"

The Google colab environment has a known issue with plugins from pybtex:
https://bitbucket.org/pybtex-devs/pybtex/issues/148/error-pluginnotfound-plugin
pybamm-team/PyBaMM#2388

A possible solution would be to add a flag to disable the parsing of bibliographic references, so this issue can be bypassed on Google colab.

Thanks
