Examples
# \donttest{
# Create a temporary file with sample book IDs
temp_file <- tempfile(fileext = ".txt")
writeLines(c("1420", "2767052", "10210"), temp_file)
# Scrape reviews
reviews <- scrape_reviews(temp_file, num_reviews = 10, use_parallel = FALSE)
#> Total book IDs to process: 3
#> 2024-10-25 03:01:56.892807 scrape_goodreads_reviews: Completed! All book reviews extracted
#> Scraping run time = 9.76628518104553
