fix: integrate options from __call

[seflue]

To be able to initialize the adapter as described in the Neotest documentation, the __call method had to be fixed. To make it more useable, I also integrated the possibility to pass the glob settings via the options table.

Perspectively it might be good to notify the user, if multiple candidates are found via globbing and let them interactively decide in this cases, which one is taken.
