Add some tweaks to sonarr notifications

[notifiarr-bot]

One thing I will mention actually: the reason I even thought about this, was because some of my users were a little confused with the notifications. For example if a whole season is downloaded at once, sometimes it looks like only some episodes were downloaded, because some messages are updated and some are added. So after the whole season is actually available, there will be messages for example for episode 1, 3 and 10 only

• Check for more than just the previous message when trying to match individual episodes in a pack
• If import notification count == tmdb episode count, update the last message with "full season imported" or similar
• add a line to the notification for packs "Episodes imported: <imported>/<tmdb total>
• make the guess matching with individual episodes look for grab or imported instead of just grab
