fix: addListener and removeListeners methods wass added to pass warning with Native Event Emitter

[TickKleiner]

While working with the module for uploading files to the server, I encountered the warnings given in the screenshots: in Metro; in_app_1; in_app_2; in_app_3
They did not interfere with the operation of the module, but they were very annoying.
I'm not very good at java and writing native modules, but based on the solution i found in the reanimated: this fix. I added the required methods to the RNFSManager.

Can we have this merged?

@itinance this is all that's required to suppress this warning.
Following the lead of react-native-netinfo, we just need this stub on Android, not on iOS.
RNFS is already properly handling the event listener removal, but here's how firebase did it if it's helpful to cross examine.

@itinance I saw this warning too and this PR fixes the problem for me. Can you help take a look and see if this PR is missing anything?

This is the commit in react-native where this warning is shown:
facebook/react-native@114be1d

The warning is added since v0.65.0.

@itinance When can we expect this PR to be released?
