Raytraverse

------------------
* moved craytraverse to separate repository, now a requirement
* implemented glare sensation model, not yet available from CLI

------------------
* first version compatible on linux systems
* changed skyres specification to int (defining side) for consistency with other resolution parameters

------------------
* include radius around sun and reflections when resampling view. for 3comp, -ss should be 0 for skyengine
* handle stray hits when resampling radius around sun
* new simtype: 1compdv / integratordv

------------------

* parametric search radius for specguide in sunsamplerpt
* integratorDS checks whether it is more memory efficient to apply skyvectors before adding points
* fixed double printing of 360 direct_views
* exposd lowlight and threshold parameter access to cli (both imgmetric and evaluate)
* changed to general precision formatting for lightresult printing
* fixed -skyfilter in pull, needs a skydata file to correctly index, otherwise based on array size
* new sampling metric normalizations, can now control logging and pbars with scene parameter

------------------

* add hours when available to skydata
* proper masking of 360 images
* integratorDS handles stray roughness from direct patch
* planmapper, z set to median instead of max, added autorotation/alignment
* bugs/features/consistency in LightResult, need better usage documentation
* directviews from cli (only works with sky)

------------------

* integrated zonal calcs in cli
* fall back to regular light result when possible (but keep area)
* fixed bugs in LightResult, ZonalLightResult
* added physically based point spread calculation that ~matches gregs gblur script, but using acutal lorentzian from reference
* added blur psf to sources in image evaluation
