Refactor LBT09 layout to work with trim_levels_to_map

[anajens]

Redesign family of functions used to create LBT09 layout to work with rtables::trim_levels_to_map. Background issue (insightsengineering/rtables#203)

Rationale: improved speed, allow users to precisely control which combinations of levels among several categorical variables used in the layout should be displayed.

Note note all of the step above may be relevant for the layout. If an update is necessary, please add the PR link below.

• tern design doc: 110_LBT09_design_doc_new_split_fun #153
• tern production code for s_, a_, layout function. Also please update relevant unit tests.
• teal.modules.clinical update. Note: Modules should aways split on the empirical map (observed combinations in the data) to make processing fast.
• TLG-C update
• nsdl.tests update to compare with STREAM

@wwojciech take a look at the design doc for LBT04 in tern as the examples there should be relevant for this function too.

Also unblocking and moving to sprint 29 as g_lineplot work is mostly done now.

Not ready for October release so moving to SME backlog.

Hi @anajens, PR (with design doc update) is ready for this issue. To simply the split map, I created new artificial indictor variable ALTAST_ind which will be used in the layout instead of PARAMCD. It seems that update of s_ and a_ is not really needed in this case. As the change to TLG-C is very subtle, let me know please if you would like to update the TLG-C LBT09 static entry in tlg-catalog to use the new layout instead of the old one.

Hi @wwojciech , I don't think I will have time to review this during the release sprint so I've moved your PR to the next sprint board.

@wwojciech just a heads up I added the nsdl.tests checkbox to the task list above.
