Add file name to errors

Is your feature request related to a problem? Please describe.
Pgtyped runs 6 threads in parallel whenever I run it, but this makes it hard to find out in which files errors are happening since they are all being processed in parallel. Adding the file name to errors would be great to prevent this.

When actively making a query this isn't really an issue, but I just changed my schema slightly and had to search through 29 .sql files

Describe the solution you'd like
File name added to error logs

This would be a fantastic add.. drives me crazy when I have many files and have to hunt down issues after a schema change

This is bugging us as well. This would be a big improvement.
