Dataset Request SRP149884

### Context

A user requested [SRP149884](https://www.refine.bio/experiments/SRP149884/non-inflammatory-tumor-microenvironment-of-diffuse-intrinsic-pontine-glioma-dipg).

### Problem or idea

It looks like Salmon timed out on a good number of the samples.

### Solution or next step

Try running it locally. This could be related to the issue I fixed where the number of reads wasn't being identified correctly.

Start by attempting to run dataset SRP149884 locally with Salmon and record which samples time out. Compare the behavior with the earlier fix for incorrect read-count identification; done means determining whether that fix resolves the failures or confirming a separate cause.
