Add callback for third party mods to override sanctions.

[Erlite]

Basically have an array of callbacks to call prior to giving a player the default sanction. Mods should be able to prevent Spyglass from giving the default sanction (probably return true to override it). Local array of callbacks, global functions to register callbacks to it.

[Erlite]

• [ ] Make a callback data struct, similar to how chat messages work. Spyglass_SanctionData
• [ ] This struct should contain the infraction score float, and a bool for whether or not it should block default sanction.
• [ ] Make an array of callback functionrefs. Input arguments should be the player, the infractions, the sanction data.
• [ ] The functionref should return the sanction data.
• [ ] Spyglass should not execute the default sanction if the bool flag on the data is true.
• [ ] AddCallback_SpyglassOnSanctionRequired() function to allow mods to add their own functions to the callback.
• [ ] Only make this function global, nothing else.
• [ ] Wrap the default sanctions of Spyglass into a Spyglass_ApplySanctionToPlayer() function. This function should have the player, their infractions and infraction score as an input.
• [ ] Spyglass_ApplySanctionToPlayer() should call all the callbacks to see if it should abort the default sanction or not. If not, apply defaults.
• [ ] Replace all sanction code in spyglass.nut with a call to this function.
