Fix setup.py.

See merge request !2

Change to pipeline usage

See merge request !1

- changed data_to_images in order to use the KM3Pipe Pipeline concept instead of iterating over the HDF5Pump.
- Added output dirpath, chunksize, compression filter and compression strength arguments
- Added CI versioning and publishing of OrcaSong via Pypi

- Add folder structure to config files folder

Add 'tight_0' timecut, which is useful for ORCA 115l mupage vs random_noise vs neutrinos classification.

- Implemented a better parser and implemented config files as an input to OrcaSong.
- Got rid of the ORCA_Geo_115lines.txt file, the detector geometry is now read from a .detx file that needs to be supplied with the input file.
- Improved general readability of the code
- fixed run_id readout
- added option to make no timecut

First prototype of docs included!
