Improve web GUI error reporting with invalid raw_csr

1

## How to reproduce Open a raw_csr dataset with an indptr file size that is invalid for the dtype specified in the sparse.toml file in the web GUI. ## What...

At the moment the shift compensation in `ApplyMasksUDF` can be a lot slower than the uncompensated one. When testing with the Radial Fourier example notebook and sparse masks, it was...

Overhaul example(s) with CoMUDF and descan error compensation

1

In particular descan error compensation has been requested often! It would be great to showcase the recent improvements by updating the example(s)

Following the example of `ApplyMasksUDF` in #1304, we could update all UDFs in LiberTEM and related projects to follow the same pattern. This feature is requested often. As an idea,...

Scheduling of background and high-performance tasks

LiberTEM can open many data sets in parallel. Some of the data might be in the file system cache and/or on fast local storage. Other data might be in other...

## How to reproduce Run at least the inline or local example for DM from the examples folder. Win11, version 3.52.3932.0. ## What happens The "local" example seems to start...

The improvement in #1397 still doesn't allow to assign to the correct part of a partition-sized task data buffer in `process_tile()` in order to combine it with `postprocess()`. This is...
