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.

Contributor guide

Research direction
Examine existing HDF5 I/O functions in Trixi.jl, such as those in src/output, to understand the data format. Then create a new function that reads a solution from an HDF5 file and interpolates it onto a uniform grid using linear or higher order interpolation. Ensure the function returns x and u arrays for plotting.
