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.
* Refactor interface to PdmObjectHandle and PdmFieldHandle
Return objects instead of passing in structures as parameters
* Add nodiscard to several functions
* Remove redundant this->
* Rename to ptrReferencedObjectsByType
* Remove obsolete code
* Fix path modification of a relative folder
Replace start token '.' with file path to the project file to make sure that the path './wells/a-1h.dev' can be imported correctly.
* Add more logging when keywords are missing from import
