[volodya-lombrozo]

In this PR I seed up the add-refs.xsl transformation and, what is the most important, I added helpful logging that shows all the hotspots.

Related to #834.

PR-Codex overview

This PR enhances the CanonicalXmir class by adding logging for the parsing process and modifies the add-refs.xsl stylesheet to include new functions for handling XML nodes, improving error messages, and adding a key for node referencing.

Detailed summary

• Added logging in the parse method of CanonicalXmir to track parsing time.
• Introduced a new xsl:key named o-by-name in add-refs.xsl.
• Modified the match condition in the with-base template to exclude base attributes starting with '.'.
• Improved error messaging for duplicate names and missing @line attributes.
• Added three new functions: eo:closest, eo:has-intersecting-route, and eo:get-route for better node handling in the XSLT.
