[Bug]: OutOfMemory errors on Android on Camera.chooseFromGallery

[ssnielsen]

Current Behavior

Since adopting Capacitor 8 and the new camera plugin (version 8.2.0), we've seen quite a few occurrences of an out of memory issue - possibly related to Camera.chooseFromGallery.

It happens across different Android versions, and across many different devices with differing amounts of memory.

Based on the stack trace from the Sentry events we see, it's seemingly related to when users are selecting items from the gallery:

java.lang.OutOfMemoryError: Failed to allocate a 75497488 byte allocation with 25165824 free bytes and 36MB until OOM, target footprint 121071528, growth limit 134217728

The onChooseFromGalleryResult in the stack trace hints to me that it's related to the chooseFromGallery.
And granted, it's quite a large file, but I don't think it's unreasonably large.

Is there anything we can tweak on our side or is this a potential bug in 8.x.x of the Camera plugin?

Expected Behavior

I think this out of memory issue is related to my issue #59 because many Android users have reported App crashes ans logs showed out of memory issue.
