Subject: [PATCH] Handle alternate COM concurrency mode

If the module is used in a program which has already initialized COM in
Apartement concurrency mode (for instance within an Electron project),
CoInitializeEx will return error RPC_E_CHANGED_MODE. In that case, try
initializing again in that mode.
