Expose well logs attached to a well path through the Python API. A new `well_path.well_logs()` returns the list of well logs, and each `WellLog` gains `channel_names()` and `well_log_data()` for reading channel names, measured depth, optional TVD MSL/RKB, and channel values. The read methods are registered on the abstract `RimWellLog` base class and use the common `RigWellLogData` interface so they work for imported, LAS and OSDU well logs alike.
