Issue reading barebones

[sebkopf]

Hi rawrr team, I'm encountering a problem with the "barebones" mode. Normal mode works great but I'm trying to read the spectra faster (without all the other information) and found the nice "barebones" mode you implemented. However, I cannot get it to work. Here's a small testfile to reproduce the issue with the reprex below. This happens for every scan (here just loading scan 1 as example). Is this the expected behaviour or some issue with my file or operating system or the barebones mode? Using the latest version of rawrr from main Github branch. This might be related to issue #84 but not entirely convinced it is.
