We're creating a 'pyosmocom' pypi module which contains a number of core Osmocom libraries / interfaces that are not specific to SIM card stuff contained here. The main modules moved in this initial step are pySim.tlv, pySim.utils and pySim.construct. utils is split, not all of the contents is unrelated to SIM Cards. The other two are moved completely.
