feat(SoloCraft): exclude map/instance from Solocraft scaling with conf

[valsan-azerty-boi]

Changes Proposed:

• Feature: Add the possibility to exclude somes map/instances from the scaling of Solocraft
• In my case I use it for a map like Alterac BG because i don't want player scaling in this

Issues Addressed:

• N/A

Tests Performed:

• Build on Debian 11 OK
• Github workflow OK on my branch
• In game tests (see below)

How to Test the Changes:

Test with excluded maps:

1. Use Solocraft.Instance.Excluded = "30,489,529,559,562,566,572,607,617,618,628" in Solocraft.conf
2. Run server
3. Queue a 80 character for Alterac (map 30)
4. Enter and see peoples with normal stats
   
   

Test without excluded maps:

1. Use Solocraft.Instance.Excluded = "" in Solocraft.conf
2. Run server
3. Queue a 80 character for Alterac (map 30)
4. Enter and see peoples with scaled stats
   
   

Sorry if my english is not in a very good state, not my native lang.
And I'm not a very C++ dev so I can make a lot of mistake, forgive me.
