Fix problem with cubes without beam header key

Note that the beam size is only used when size filtering. This is typically not done anymore. Either way, the bug should now be fixed. The lines extracting the beam information are now in the 'sizeFilter' part of the code, and the beam is set to zero if no information is present in the header.
fixed NaN's in mom0

Voxels = NaN in original cube now become 0's after multiplication of the cube by the binary mask. Therefore, they do not contribute to the moment-0 image, nor do they result in a NaN pixel.
fixed NaN's in 'negative rms'

replaced cube.min() with nanmin(cube) to calculate histogram limits
fixed a few issues related to NaN's

1) Set NaN's to 0 before smoothing. SciPy smoothing functions would otherwise grow the NaN region
2) Set voxels that are NaN in the input cube to False in the final binary mask
minor bug fix
Update README.md
Update README.md
fixed handling of NaN's for moment1
minor edit
keep NaN's for rms, replace with 0's for smoothing
Create parametrisation.py

Separate module/function that calls the parametrization and returns the input parameter array(s) with the new parameters appended.
Update store_ascii.py
Update sofia_pipeline.py

Moved parametrization to a separate module. Enabled option to choose parameters that are included in the ascii output catalog.
