feat: Migrate option file selector to SAF

[X1nto]

This gets rid of external file access requirements by moving the patcher options path selector to Storage Access Framework. Because of this change, it has become necessary to 1) separate folder and file selector actions and 2) copy selected folder/file to the app's internal storage. Internal storage refers to Filesystem.tempDir.

androidx.documentfile was added to handle SAF and everything related to external storage permissions have been removed.

If we exit the app does it remove these files?

[Ushie]

Yes, it's stored in the same place as the temporary files generated for patcher

The temporary files will be gone after an app restart and won't be present if manager attempts to use saved patch options. This is partly why I chose not to use SAF when implementing patch options.

Suggested change

	documentfile = { group = "androidx.documentfile", name = "documentfile", version.ref="documentfile" }
	documentfile = { group = "androidx.documentfile", name = "documentfile", version.ref = "documentfile" }

@X1nto app restarts still need to be handled, since the temporary directory will be cleared on restarts. To fix this, you could:

• Create a new data class for holding the SAF URI (and whether or not it is a folder). The data class probably needs to be java.io.Serializable and/or Parcelable.
• Change StringOptionEditor to : OptionEditor<Any>.
• Set it to a string whenever a string is specified and the custom type otherwise.
• In Options.kt, define and implement a json object representation for the custom type whenever a patch option with the string type is encountered. The SAF URI will be valid even after a restart and can be persisted in the database.
• Move the SAF copying logic and transform the custom types into strings right before passing the options to runtime.execute in PatcherWorker.kt
