Add support for non-ordinal patching

Example usage:

// In your DLL
static const int D2CommonImageBase = 0x6FD40000;

static ExtraPatchAction extraPatchActions[] = {
    //{ 0x6FDB6300 - D2CommonImageBase, &STATLIST_FindStatIndex_6FDB6300 , PatchAction::FunctionReplaceOriginalByPatch },
    //{ 0x6FDB6C10 - D2CommonImageBase, &sub_6FDB6C10, PatchAction::FunctionReplacePatchByOriginal },
    //{ 0x6FDB64A0 - D2CommonImageBase, &sub_6FDB64A0, PatchAction::FunctionReplacePatchByOriginal },
    //{ 0x6FDB6920 - D2CommonImageBase, &STATLIST_FindStat_6FDB6920, PatchAction::FunctionReplacePatchByOriginal },
    //{ 0x6FDB6970 - D2CommonImageBase, &STATLIST_InsertStatOrFail_6FDB6970, PatchAction::FunctionReplaceOriginalByPatch },
    //{ 0x6FDB6AB0 - D2CommonImageBase, &STATLIST_UpdateUnitStat_6FDB6AB0, PatchAction::FunctionReplaceOriginalByPatch },
    //{ 0x6FDB63E0 - D2CommonImageBase, &STATLIST_GetTotalStat_6FDB63E0, PatchAction::FunctionReplaceOriginalByPatch },
    { 0, 0, PatchAction::Ignore}, // Here because we need at least one element in the array
};
