Consider using camelot instead of tabula

[huin]

Camelot is a Python based library that would remove the need to have Java installed on the system. It still needs an external program (Ghostscript), which should be weighed in comparison to requiring Java.

[huin]

Camelot also has a web-frontend (Excalibur), this should be checked for suitability as to if it can export templates for inclusion in travdata's configuration.

[huin]

This might be a costly approach, as initial attempts to use the Excalibur frontend for Camelot seem to show that it doesn't seem to be actively maintained (versioning problems with its dependencies - e.g. camelot-dev/excalibur#178 ).

camelot-dev/excalibur#176 indicates signs that it has been forked at least once, including Camelot forking to https://github.com/py-pdf/pypdf_table_extraction. However, this fork seems to be incomplete, at least not updating links/docs/branding (per py-pdf/pypdf_table_extraction#9).
