Nuradiomc

bugfixes:
- Fixes that the generic detector crashes for certain detector files.

new features:
- add a numerical raytracer depending on the radiopropa code
- major change in the declaration of mediums at the back end, at the front end nothing changed.
- Added neutrino direction reconstruction module and example on how to use it.
- inheritance of ray tracers form a base class
- changes to the eventbrowser in order to read RNO-G data
- add sphericalWaveFitter module
- add directory RNO_data with an example reconstruction for RNO data and the calculation of the cable delays
- add Genie HEDIS (BGR18) cross section as an optional cross sec model
- add handling of multiple reference channels and stations to generic detector
- add thermal noise generator that fulfills phased array trigger
- add a basic uproot data reader for RNO-G data
- add option to simulate emitters
- added helper function for cosmic ray flux models
- speed improvements of ARZ model through use of numba

bugfixes:
- correct volume extension depending on zenith angle range when running with
secondaries
- corrected get_hilbert_envelope(_mag) in BaseTrace to actually return the Hilbert envelope and simplified resamle function

new features:
- Veff utility can now calculate effective volumes for fine zenith angle binning
- Monte Carlo info introduced in .nur files via Particle and generator_info

bugfixes:
- fixed rare cases where the Cpp implementation of the analytic ray tracer did not find a solution

- NuRadioReco is merged into the NuRadioMC repository. No new features were added and everything works (e.g. the imports)
as before but the NuRadioReco code is now part of the NuRadioMC github repository to simplify code development where NuRadioMC
changes depend on changes in NuRadioReco.

new features:
- users can specify a different bandwidth for each channel in the channelBandPassFilter and channelGenericNoiseAdder module
- new coreas read in function to generate signals for a grid of stations
- added simulation of galactic noise
- new phased array trigger module
- eventWriter: Add option to specify number of events per file

bug fixes:
- Added if check in voltageToEfieldConverter.py under method get_array_of_channels() to see if sim station is initialized
- trigger modules set the trigger time to 0 in case not trigger was recorded. This lead to problems, and wrong total trigger times, if multiple triggers were recorded. Now, no trigger time is set if not trigger was found.
- made detector_sys_uncertainties compatible with python3 and detector updates
- Typo in antennapattern.py; processing antenna responses fails. replaces s_parameteres with s_parameters

new features:
- major change in internal looping. Now, the radio signal from each shower is calculated and signal arrival times
(from different shower, ray racing solutions and receiver positions) that cluster together are simualted as one event
- merge hdf5 utility has multithreading option (and was refactored -> function names changed)
- distance cut can sum up all sourounding shower energies to properly account for possible interference
- noise temperature can be specified per station and channel
- trigger thresholds can be specified per channel
- bandwidth can be specified per station and channel
- specifying the detector simulation became easier (check out the updated examples)
- memory consumption was optimized to stay <4GB per core
- random realization of showers are saved so that triggered events can be resimulated using the same random realization
- added option for noiseless channels in a "with noise" simulation
- add option to generate events on the fly and pass them directly to the simulation part (no need to save input hdf5 files anymore)
- added uncertainties to CTW cross sections
-

bugfixes:
- Fixed issue with merge hdf5 utility so that "event_group_ids" are properly unique
