(wip) linux support for parser

[ellieplayswow]

chunking through this bit by bit, currently it builds and starts running via dotnet but fails -

PARSER STAGE: ContributorDataMerge...
FILE: ./DATAS/00 - DB/ObjectDB_Conditionals.lua

Press Enter once you have resolved the issue.

due to a mix of issues on my host machine i can't really run the parser, even with wine. opening this pr mostly so anyone can shout at me if this isn't wanted :) will leave it marked as a wip until it works fully and i'm happy enough with it

The current library depends on the .NET framework and needs to be migrated to .NET to achieve cross-platform compatibility.
However, previous migrations have encountered some problems, so we have been temporarily shelved, and there are currently no plans for further migration.

[NORPG]

The main problem is that NLua (Lua parser for .NET) seems to have inconsistent behavior, and the root cause has not yet been found.

[NORPG]

Currently, the NLua within the parser is compiled by ourself, not captured from the package; it's unclear whether this is a compilation-time setting issue.
