Fix spelling

Fixes #69

Checks for SpatParams caused errors if parameters weren't supplied in the right
order. Fixed by making setParams a method and reordering the update list
before setting parameters.

Fixes #64

Also remove lingering references to phenoData and featureData

Also add new BASiCS tests

Also add new BASiCS tests

Fixes #56

These would sometimes error due to sampling of example dataset

Fixes #36

Store gene parameters in data.frame rather than separate vectors. Forces them
to be same length and allows more independence between gene parameters and
nGenes. Checking for differences between the number of gene parameters and
nGenes, and sampling if necessary, is now done in `lun2Simulate` rather than
`validObject`. The same is true for nCells and lib.sizes.
