Find way to print `missing` df when `check_tbl_values_required()` fails

[annakrystalli]

Currently I'm just attaching a tibble of missing required rows that should be present given.

It would be nice to be able to print this to the console in a pretty way.

Briefly experimented with the following:

library(hubValidations)
hub_path <- system.file("testhubs/flusight", package = "hubUtils")
file_path <- "hub-ensemble/2023-05-08-hub-ensemble.parquet"
round_id <- "2023-05-08"
tbl <- read_model_out_file(file_path, hub_path)
res <- check_tbl_values_required(tbl[-(24:25), ], round_id, file_path, hub_path)
res
#> <warning/check_failure>
#> Warning:
#> Required task ID/output type/output type ID combinations missing.  See
#> `missing` attribute for details.

# Print tbl with cli - NOPE
c(names(res$missing), as.vector(t(res$missing))) %>%
    cli::ansi_columns(
        fill = "rows",
        max_cols = ncol(res$missing)) %>%
    cli::boxx()
