Round table

Sebastian: made some progress; now preparing tests. Also taking a look at some Jira issue; able to reproduce the problem with the help of Bertrand.

Philippe: fixing a problem in the scaling of `TTreeCache`.

Jonas R: several things last week: fixed some problems with RooWorkspace IO, spent quite some time with some guy in the forum, and also some attention/fixes to Garima's code generation.

Javier: addressed the comments in the last review of RNTuple late model extension PR (part 1). This part 1 is now merged; created a PR for the second (last) part, that completes this feature.  Had a meeting with Marcin Nowak to talk about next steps.
Also worked in fixing a cling issue and a number of code reviews.

Giovanna: work integrating S3 backend. Performance is pretty low, esp. for writing. Looking also into supporting the Amazon SDK (apart from Davix).

Garima: some progress with RooFit code squashing. Also, dedicated some time to work on the CHEP contribution.

Dante: worked on the CHEP project: currently testing/analyzing the results that have for the benchmarks.

Baidyanath: worked on cppyy. Taking a look at an issue with lamba expressions.

Jakob: opened a PR for supporting fields of type `std::unique_ptr` in RNTuple. Also created a PR for enabling the use of Index64, i.e. 64bit offsets, which enable the storage of large events and/or collections.

Lorenzo: working on minimizer for CHEP. Also some work with Sanjiban on GNN.
