Adds in a fix to the edge case where we have a path with only one road segment.

Updates the plotting module to break out the plots into separate files and adds a new file to plot a trajectory segment.

Adds an optional flag filter_to_largest_component to the method NxMap.from_geofence(), set to True by default. When this flag is false, we will not extract the largest strongly connected component which could lead to routing failures but will keep the entire graph rather than opaquely removing some of it that is not strongly connected.

Pull request overview

This PR adds support for handling disconnected graph components and refactors the plotting utilities into a more modular structure. The changes introduce a filter_to_largest_component parameter (defaulting to True) that allows users to optionally keep all graph components instead of only the largest strongly connected component, which could prevent routing failures in some cases. Additionally, the PR fixes an edge case where paths with only a single road segment were not handled correctly.

Key changes:

• Adds graceful handling of disconnected graph components by catching NetworkXNoPath exceptions and returning empty lists
• Refactors monolithic mappymatch/utils/plot.py into separate module files for better code organization
• Fixes edge case logic for paths with single road segments (changed from n < 2 to n == 0 and len > 1 to len > 0)
