This additionally refactors `image()` to be simpler by taking advantage of the fact that we only want one image. Additionally, this codepath avoids the system-level caching of image data that can help reduce peak usage. We have applied an autorelease pool to the Obj-C code as well, as there appear to be a lot of autoreleased values used by AppKit.framework Finally, it applies a similar refactoring to `text()` for simplicity and removal of memory leaks due to incorrect object retaining assumptions.

In summary, this PR removes the last of the memory leaks in the macOS clipboard implementation. Specifically, it does two things to accomplish this:
This additionally refactors
image()to be simpler by taking advantage of the fact that we only want one image. Additionally, this codepath avoids the highly aggressive system-level caching of image data that can help reduce peak usage. We have applied an autorelease pool to the Obj-C code as well, as there appear to be a lot of autoreleased values used by AppKit.frameworkFinally, it applies a similar refactoring to
text()for simplicity and removal of memory leaks due to incorrect object retaining assumptions. After a lot of investigation, this seemed to be the best path forward (as previously noted by #97).Its worth noting that some of the memory growth caused by these functions would have gone away after 5-10 seconds of not calling into the clipboard. However, some use cases require calling into it frequently so this isn't always an option for users.
