Compute SSCI for .fls, .ptx or .xyz files

SSCI(
  input_fls = "*.fls",
  align_to_terrain = T,
  voxel_size = 0.1,
  slice_thickness = 0.5,
  angular_resolution = 360/2560,
  CROP_SOR_xyz = F,
  crop_square_length = 10,
  crop_circular = F,
  crop_circular_radius = 10,
  save_steps = F,
  plotting = F
)

`input_fls`	A .fls, .ptx or .xyz file. Note .fls requires a Main file in the same folder as the .fls file.
`align_to_terrain`	Logical. Should a slope correction for SSCI be performed. Default TRUE.
`voxel_size`	Voxel size (in meter) for ENL computation. Default 0.1 m.
`slice_thickness`	Thickness (in meter) of vertical layers for ENL computation. Default 0.5 m.
`angular_resolution`	Angular resolution of the scan, i.e. 360/number of points. Default 360/2560.
`crop_square_length`	Half edge length (in meter) of squared crop along xy axis around scan center. Default +-10.
`crop_circular`	Logical. Should points be clipped circular around the (0,0,0) position. Default FALSE.
`crop_circular_radius`	Clip radius (in meter) if crop_circular=TRUE
`save_steps`	Logical. Should aligned point clouds and filter clouds be saved. Default TRUE.
`plotting`	Logical. Should the MeanFrac polygons be plotted. Note: This may takes a long time. Default FALSE.
`CROP_SOR_XYZ`	Logical. Should a statistical outlier removal filter be applied and point cloud be cropped. Default FALSE.
