[Duplicate detector] inform which file couldn't be parsed

[przemekrcloudity]

When a duplicate detector fails to parse file, it informs the user in which line the error occurred but doesn't provide information about which file it was in.

ERROR running hardis:project:metadata:findduplicates:  Non-whitespace before first tag.
Line: 0
Column: 1
Char: a
[sfdx-hardis] hardis:project:metadata:findduplicates execution time 0:00:01.823

I think it would be helpful to inform the user about the file path that caused the error

Error reproduction steps

In some XML file, in our case profile definition file, add text by mistake that would make file unparsable, like this:

adas<?xml version="1.0" encoding="UTF-8"?>
<Profile xmlns="http://soap.sforce.com/2006/04/metadata">
    <application
....

After that, run duplicate detector
