missing: hicstraw python module

[ChristopherBottomsOMRF]

When I try the example code to run the HiCrayon container, it complains that hicstraw is missing.

apptainer exec hicrayon.sif Rscript run.R
Loading required package: shiny
[1] "Running HiCrayon on Regular mode"
Error in py_run_file_impl(file, local, convert) : 
  ModuleNotFoundError: No module named 'hicstraw'
Run `reticulate::py_last_error()` for details.
Calls: <Anonymous> ... ..stacktraceon.. -> <Anonymous> -> py_run_file -> py_run_file_impl

Thank you for all of your work on this project!
