Overly Verbose Router Look ahead warnings

[ZohairZaidi]

Implementation of Sample Location Warnings in Route Verbosity

Proposed Behaviour

The system should integrate existing warnings regarding the unavailability of sample locations for specific resource types (SOURCE and OPIN) into the route verbosity system.

Current Behaviour

Currently, these warnings are produced as runtime output without any verbosity control.

Possible Solution

Integrate Warnings into Route Verbosity
