[Baldur's Gate 3]: Various bug fixes

[TheForgotten69]

Hi there!
Just began to use this plugin and it's great. Lots of great ideas and features from @daescha thanks! But there are a couple of bugs at the moment that are addressed in this MR:

1. Missing libraries from LSLib: the automatic download works fine but not all mandatory DLLs are extracted
   Current error:

The system cannot find the file specified.

2. Regex issue with mod names (Such as Animate Dead++)
   Current error:

hi @TheForgotten69! I am very happy someone else got the chance to test this before the next release of MO. All your changes look good!

@Holt59 I recommend merging this, when you get a chance ☺️

as a sidenote: obviously those files from lslib you needed were not needed on my machine. Makes me wonder if there are other ones other people may potentially need... but problem for another day. If you have improvements/criticisms beyond just bug fixes though I would love to hear/see them @TheForgotten69 😌

[TheForgotten69]

Hey @daescha I'm happy to test your work! 😊 Honestly, it's the best plugin all around and much better than what's available or even the BG3 mod manager, imo.
I'm especially pleased by the automatic conversion of generated mods to pak!
Regarding LSLib, I guess it might not have all .NET assemblies installed, but yeah I thought of maybe just dumping the whole thing rather than being selective since it's just a few MB, but it's also working for me now that way.
Honestly the plugin is pretty powerful as is, but one potential enhancement might be to list conflicts thanks to LSLib, wdyt? i guess it's possible to store some sort of table where each mod has its pak content associated to compare but you definitely know this more than me. No idea if it's possible in a custom plugin like this but I guess it's pretty niche 🤔

[daescha]

Yeah that would definitely be nice. if you wanted to, you could unpack all your packs into each mod folder and itd show conflicts based on file paths that way - thatd work for files that go in Generated folders at least. Of course the pak loading process in bg3 is not that simple for all the lsf files, they get merged based on xml elements somehow, youd basically have to recreate the games pak loading mechanism to show that part properly.

[TheForgotten69]

Yeah that could get messy real quick, maybe something that just scans the files within pak and report if it ever find matches? We could have a hash base somewhere in the data plugin folder?
Also just noticed that the "Check for updates" for mods seems to always crash my Mod Organizer instance, have you the same behavior @daescha ?
