dataset loads/reads "twice" into gfci.discrete

[kingfish777]

When I load a dataset into rcausal/gfci.discrete, it seems to load twice, effectively taking twice as long ===>

`> rcausal::gfci.discrete(dat)
node_names: ade
value: [1] 0 1

node_names: medication
value: [1] 0 1

node_names: diabetes_mellitusCOMMA_nonHYPHENinsulinHYPHENdependent
value: [1] 0 1

node_names: ligation
value: [1] 0 1

node_names: insulin_sensitivity
value: [1] 0 1

node_names: ade
value: [1] 0 1

node_names: medication
value: [1] 0 1

node_names: diabetes_mellitusCOMMA_nonHYPHENinsulinHYPHENdependent
value: [1] 0 1

node_names: ligation
value: [1] 0 1

node_names: insulin_sensitivity
value: [1] 0 1
`

Going to try PC and FGeS after this.

This is not the case with PC or FGeS (though loading is slow, it is twice as fast as with GFCI)

I'll take a look at the data loader.
