Remove flourinated natural products found by Adelene

I found 64 CNPs forming 23 CF2 homologous series.

(shared corresponding plots of molecules with @Kohulan)

There could be more fluorinated CNPs within COCONUT, but these are just those I've found so far. fluorinated_cnps_to_remove_from_COCONUT.csv
