Numberfire IDP bug

[TheMathNinja]

Just noticed that when scraping NumberFire IDP data, rather than using the name idp_sacks like for FFT and FantasySharks, the NumberFire scrape assigns idp_sack to their sack projection.

Therefore this scrape:

 ffanalytics::scrape_data(
  src = c( "FantasySharks", "FFToday", "NumberFire"),
  pos = c("DL", "LB", "DB"),
  season = 2024,
  week = 0

returns df's with idp_sack and idp_sacks variables. NumberFire should be renamed to idp_sacks.
