Store encoder-steps at shutdown, consider at startup

Browse Source 
shutdown:
    - add functions to read/write last encoder steps from nvs
    - store encoder steps at shutdown

guide:
    - add function to calculate layer count from cable length
    - read last encoder-steps at startup
    - if length >2m calculate layers, dont home
    - home at move-to-zero when not done at startup

encoder library:
    - add function to set encoder steps

control:
    - read last encoder-steps at startup
    - apply last steps if >2m
