Difficult to find image `.tex` files in case of error

[siefkenj]

If the compilation of a tikz figure fails, the user may want to inspect the .tex file that was attempting to be compiled. The CLI currently gives the name of the .tex file that failed, but not the path, making it very difficult to track down the file to run further tests.

I suggest that in the case of an error a message like,

Manually inspect the `.tex` file at: ...

be printed.

This probably belongs to PreTeXtBook/pretext ?

Does core handle the creation of temporary directories? Or you're just saying since core prints the error, it should format it?

The compilation of a tikz figure happens in the code of PreTeXtBook/pretext so I'm guessing we're just passing along a message from there. Haven't looked closely though.
