Perform path resolution function in Meshroom core

[demoulinv]

Description

This PR implements the path resolution function within meshroom core in the new file fileUtils.py. That resolution was formerly implemented in meshroom ui components. The original method still exists but has been cleaned up and calls the new ones.

The path resolution function replace all the fields in a template name by their corresponding value extracted whether from an input filepath or a viewpoint.

A dictionary is built from the input filepath or the viewpoint. The fields to be replaced in the template name are supposed to be found amongst the keys of that dictionary. In case a key does not exist the corresponding input field is discarded to build the resolved path. Such a case can occur for example if the field is used in the template whereas the input filepath does not contain any value corresponding to a frame number.

The way the replacement is done has also been optimized using regex sub function.

Pull Request Overview

This PR refactors path resolution functionality from the UI layer to the core layer by implementing a new fileUtils.py module in meshroom core. The refactoring centralizes template-based path resolution logic that replaces field placeholders like <FIELD> with actual values extracted from file paths or viewpoints.

Key changes:

• Creates new fileUtils.py with functions for extracting file elements, view elements, and pattern replacement
• Simplifies the UI filepath.py by removing duplicate path resolution logic and delegating to the new core functions
• Optimizes replacement implementation using regex substitution instead of iterative string replacement
