Convert Numbers into Padded Strings for Easier Group Numbering

## Examples

```
# Useful for easier group numbering so groups are ordered as intended
# Expects a numeric vector of numbers to convert to padded numbers
regular_numbers <- 1:19
padded_numbers <- group_numbers(regular_numbers)
# The padding matters when creating labels for groupings
# as numbers will be converted to characters if attached to strings.
# Sorts as expected:
sort(regular_numbers)
#> [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
# Does not as a character:
sort(paste0("group_", regular_numbers))
#> [1] "group_1" "group_10" "group_11" "group_12" "group_13" "group_14"
#> [7] "group_15" "group_16" "group_17" "group_18" "group_19" "group_2"
#> [13] "group_3" "group_4" "group_5" "group_6" "group_7" "group_8"
#> [19] "group_9"
# Will sort as expected when padded:
sort(paste0("group_", padded_numbers))
#> [1] "group_01" "group_02" "group_03" "group_04" "group_05" "group_06"
#> [7] "group_07" "group_08" "group_09" "group_10" "group_11" "group_12"
#> [13] "group_13" "group_14" "group_15" "group_16" "group_17" "group_18"
#> [19] "group_19"
