More numeric IRC reply constants

[heavyjoost]

🚀 Changes proposed by this PR

This adds more numeric IRC reply constants that I came across while needing two (338 and 378) that were missing.

🧰 Type of change

• New feature (non-breaking change which adds functionality).

📝 Notes to reviewer

Constants as specified by https://modern.ircdocs.horse.

I added two constants (RPL_INVEXLIST and RPL_ENDOFINVEXLIST) which are currently the same as RPL_INVITELIST and RPL_ENDOFINVITELIST. According to the reference docs the latter two more commonly use 336 and 337, so this is something that might need work. I did not change those as they already present. I also did not sort the constants by value as it seems like the current order was not sorted on purpose.

Edit: regarding the invite list, this suggests (to me) that the name might have been an error in the original RFC: "This numeric is sometimes erroneously called RPL_INVITELIST, as this was the name used in RFC2812."

Any questions, please let me know!

Honestly, I'm fine if we change it, as I suspect it's a rare reference, and if it's already incorrect, it would be quite odd for someone to be relying on it. Also trust ircdocs.horse.
