Description

Quoting @ranocha:

One feature I would like to have in 1D concerns visualization: Instead of using trixi2txt from utils/trixi2txt.jl to write a .txt file and read that again in Julia to plot something, could we just have a function returning the respective x and u arrays directly? Then, users can just create their own plots in Julia directly without having to deal with another set of files.

Research direction
Examine the existing `trixi2txt` utility in the source code to understand current HDF5 loading. Create a new function that reads an HDF5 file and returns `x` and `u` arrays for 1D problems, interpolated to equidistant points. Consider placing it in a post processing module and test with example solutions.
