`build_feature_tables` references file path that doesn't exist

[jaeddy]

These lines in build_feature_tables.R seem to be outdated (on the feature/feather_file_structure branch here):

  cat(crayon::magenta("Importing feather file for features."), fill = TRUE)
  features <- read_iatlas_data_file(feather_file_folder, "/SQLite_data/features.feather") %>%
    dplyr::rename(name = feature) %>%
    dplyr::mutate(class = ifelse(is.na(class), default_class, class))
  cat(crayon::blue("Imported feather file for features."), fill = TRUE)

Neither the SQLite_data/ folder nor the features.feather file seem to exist under feather_files/:
