[BUG] The cache entry has not been truly deleted after expiration

[cyjaysong]

Describe the bug
The cache entry has not been truly deleted after expiration. this will cause the program to consume more memory to store invalid data.

To Reproduce
see code in https://github.com/kataras/iris/blob/main/cache/entry/entry.go

The program logic only determines whether the expiration time has been reached. If it expires, it will be reset to the new content on the next request. If no new requests arrive, expired data will continue to occupy memory

@cyjaysong thanks, I have re-factored the code, so you can read my solution, the commit contains new features as custom max age function and custom storage, maybe your issue is solved as well, if so you don't need to do anything at all :) Check: 28f49cd
