Problems with import paths of mapping json

[THuckemann]

On some setups (4K Setup, Selene so far) the mapping json files of instruments are not properly installed.
They are available at location of the qumada repository but not copied to the site-packages location of the environment when
doing pip install of qumada. This results in some path not found exception when trying to map the instruments.
Quickfix is to simply copy paste them there.
