Add nostr-tools dependecy about nostros

[arejula27]

On this case i think you made the correct decision, good luck. I cant wait for using nostros :D

I saw you want to manage the ws connections after a long inactivity time, with this library it is possible too, you can develop the logic and call connect/ close connection on each relay

Hi @arejula27, Nostros already does a limited use of nostr-tools

nostros/frontend/Components/ConversationPage/index.tsx

Line 14 in df8a69d

import { decrypt } from 'nostr-tools/nip04'

Initially I wanted to use it as base library of the app, but I ended up facing 2 main problems:

• nostr-tools implements a version of ECMAScript not compatible with Android. If I remember correctly, it requires 2021 and Android is limited to 2019.
• React-Native has a single thread to manage everything related to JS (views included), so doing an intensive use of background tasks (for example relays communication) affected really badly to the performance resulting even in the app completely freezing for seconds.

This is why I decided to re-implement everything that can be parallelized in Java, it was the only way to have a good performance.

Have you tried @jb55's nostr-js?

Yes I did but it was missing some functions I needed, I assumed nostr-tools was a most recent version and decide to go forward with the Java version. The main problem as I said is that the background jobs with JS affects a lot the UX
