I've held off on this in the past, because I was concerned about the
security issues related to Java object deserialization. To circumvent
that, I've written a parser that understands just enough of the Java
Object Serialization format to parse FreeOTP 2 backups.
Unfortunately there are a number of issues in FreeOTP 2 that may result in
corrupt backups. The importer warns the user about this and tries to
salvage as many entries as possible.
Gets rid of all of the custom logic we had for notifying the
RecyclerView about changes in the entry list. This will allow for more
simplifications in the future around non-persisted changes to state in
the entry list.
A neat side effect is that any filtering/ordering changes in the entry
list are now also animated: https://alexbakker.me/u/4a4ie5yzpj.mp4
This touches the fundamentals of the entry list, so lots of careful
testing required.
The following crash could occur when trying to import an icon pack for
which an empty folder still exists on disk:
```

To reproduce on a debug build of Aegis with the latest aegis-icons
imported into the app, run the following commands and then try to import
the same aegis-icons ZIP again:
```
$ adb shell
$ su
# rm -r /data/data/com.beemdevelopment.aegis.debug/files/icons/c1018b93-4e8c-490a-b575-30dde62a833e/20230523/*
```
This fixes the following crash I noticed in the developer console:
```
