banip: release 1.8.8-1

- introduced a shared named nft limit (loglimit) referenced by
  all log rules instead of per-rule limits, aligning with kernel printk rate limits
- added new 'ban_logratelimit' and 'ban_logburstlimit' UCI options for tuning
   the shared log limit; setting ban_logratelimit=0 disables nft-side rate limiting
   entirely (useful for ulogd or other userspace log handlers that bypass printk)
- LuCI: made the new UCI option available (Log Settings)
- readme update
