fix: Event unsubscribe not working correcetly when using same key for multiple events (#1309)

### Problem description
<!-- Describe the bug that you fixed/feature request that you
implemented, or link to an existing issue describing it -->
Fixed possible bug of `EventManager::unsubscribe`
`std::map` only allows unique key, but the same token can subscribe to
multiple events.
https://github.com/WerWolv/ImHex/blob/1a2a926b772f32d4f5e4c723c48e0e6e65a16b0a/lib/libimhex/include/hex/api/event.hpp#L104-L107
If the previous token has already subscribed to an event, then when
subscribing again, `getTokenStore().insert` will not do anything
(Because its type is `std::map`)
https://github.com/WerWolv/ImHex/blob/1a2a926b772f32d4f5e4c723c48e0e6e65a16b0a/lib/libimhex/include/hex/api/event.hpp#L122-L134
At this point in `unsubscribe`, the `iter` may not be able to find the
correct event and erase it
### Implementation description
<!-- Explain what you did to correct the problem -->
Change `tokenStore` to `std::multimap` instead of `std::map`, which
cannot unsubscribe multiple events correctly
### Screenshots
<!-- If your change is visual, take a screenshot showing it. Ideally,
make before/after sceenshots -->
### Additional things
<!-- Anything else you would like to say -->
