Graceful fossil error handling

[Oliveriver]

Brief Description of What This PR Does

Ignores corrupt fossil files to prevent crashes when opening the Thriveopedia.

I went for the nuclear option of just wrapping the whole loading process in a try-catch block and printing the error. That may lead to error spam if a user with a corrupt fossil repeatedly opens and closes the Thriveopedia.

The lead programmer for Thrive is currently on break until 2023-01-02. Until then other programmers will try to make pull request reviews, but please be patient if your PR is not getting reviewed.

PRs maybe merged after multiple programmers have approved the changes (especially making sure to ensure style guide conformance and gameplay testing are good). But PRs may need to wait until the lead programmer is back from the break.

I still like the approach of allowing corrupt entries just for the sake of telling players they have corrupt fossils but, this is good enough I guess.

It would certainly be possible to update that in future using a null check to display something else.

That's good, as for now, this looks fine to me
