loosen overly restrictive dependencies

[dojoteef]

@martiansideofthemoon here are the dependency changes i mentioned to the pyproject.toml. It might be possible to further loosen the requirements, tough supporting torch>2.0 and getting rid of the mandatory install of pysqlite-binary was enough for my workflow. Since python already comes with a sqlite3 module, there's no need to enforce the use of pysqlite-binary (which as I mentioned in Slack just failed to install for me due to a missing wheel on my platform). If someone does want it installed, they can do so with pip install factscore[pysqlite-binary]
