I implemented decoding of the [O|H]PLMNwAcT elementary file in pySim.

Here https://github.com/lazlo/pysim-dec-plmn you will also find unit tests for the code I wrote.

Let me know if I should further refactor the code (maybe to use more of the existing conversions functions in pySim/util.py). I'm aware it is not the most elegant code but it does its job.

Best,

Lazlo
