High memory usage issue

[alexisbar]

Hello,

I faced a memory issue in my app that is related to MixPanel's swift SDK.
This has been really visible when I started using an extension, as the memory limit is really low in these lands. (24Mb for a Notification Service Extension)
After some debugging I found that it was due to a call that was made upon each process launch:

Mixpanel.mainInstance().people.unset(properties: ["myAwesomeProperty"])

When receiving a lot of notification in a row, this was causing my extension to hit the memory limit.

This is easily reproductible in any application by implementing these lines of code:

for _ in 1...10000 {
    Mixpanel.mainInstance().people.unset(properties: ["myAwesomeProperty"])
}

When triggered upon app launch, this causes a really high memory usage

iOS 16
Mixpanel-swift (4.0.2) installed via cocoa pods

I'm seeing the same issue. When offline and tracking many events, the memory grows significantly.
