[BUG] Crash from invalid regex

[Gjum]

When RegexFinder processes an invalid regex, the game crashes.

Expected behavior
AdvancedChatCore should handle any and all possible errors that could occur while handling a chat message.

While invalid regexes could additionally be rejected in the editor gui and never saved to begin with, that alone would not be very robust.

Minecraft Info

• AdvancedChatBox-1.18-1.1.3
• AdvancedChatCore-1.18.2-1.5.0
• AdvancedChatFilters-1.18.2-1.2.3
• AdvancedChatHUD-1.18.2-1.3.2
• AdvancedChatLog-1.18.2-1.2.1
• AdvancedChatMacros-1.18.2-1.0.0

To Reproduce

1. edit the regex of one of the chat tabs in, I believe, AdvancedChatFilters
2. while editing the regex, it becomes invalid due to being in the process of being edited
3. with the editor still open, the game receives a chat message
4. the game crashes with the stacktrace
