Closes #177

This PR replaces the complicated legend creation with annotations. In this way we are also able to retain the ggplot object properties and (for example) add custom labels to the plot. See example of a resulting plot below.

@maurolepore - I started this PR to have my work online but it is a draft and I am still going to do quite a bit of refactoring to simplify how the plot is created before I consider it ready for review.

It looks like we need to use_package("ggrepel").

Error: Error in loadNamespace(x) : there is no package called ‘ggrepel’

Yes, definitely. I'm just fooling around for now. Once I decide on the packages I will add them to imports, etc.

Is this meant to min(.data$year) here, versus min(data$year)?

Maybe it's best to use a different argument name than data since it's so easily confused with .data? Maybe it doesn't make a difference? 🤷🏻

here's an example of a case where it might matter...

library(dplyr)

data <- tibble::tribble(
  ~name,     ~gender, ~grade,
  "Bill",    "m",     65L,
  "Bob",     "m",     73L,
  "Mary",    "f",     98L,
  "Melissa", "f",     87L
)

data %>% 
  filter(gender == "f") %>% 
  mutate(mean(.data$grade))
#> # A tibble: 2 x 4
#>   name    gender grade `mean(.data$grade)`
#>   <chr>   <chr>  <int>               <dbl>
#> 1 Mary    f         98                92.5
#> 2 Melissa f         87                92.5

data %>% 
  filter(gender == "f") %>% 
  mutate(mean(data$grade))
#> # A tibble: 2 x 4
#>   name    gender grade `mean(data$grade)`
#>   <chr>   <chr>  <int>              <dbl>
#> 1 Mary    f         98               80.8
#> 2 Melissa f         87               80.8

in this case I actually meant min(data) not min(.data)

I added additional_line_metrics because they were defined but not used.
