[DanikVitek]

Adds deserialization path tracking, for better descriptiveness.

Fixes #22.

Hi, thanks for the contribution. Can you provide a sample of how the error looks like before vs now?

@PgBiel Example: line 22 -- et-ale is not a valid term
In this case I'm using color-eyre, which displays source errors as well, so you can see the "Error 1" as the previous error message, and "Error 0" as a new one
