Replacing data provider with native version

[liketurbo]

The lite client tonlibjson, currently in use, comes with slow compilation time, and as a non-native, it is harder for non-C++ developers to inspect and subsequently make changes to the code.

---

The proposal is to replace it with the native version. I have also opened a TON bounty footstep for this issue, which you can find here: Rust Lite Client Instead of tonlibjson.

1. Do you feel that this proposal is well-motivated and worth discussing further?

2. [In case of a positive answer from 1] How should it be pursued further?

   @hacker-volodya has suggested replacing it with the tonstack/lite-client he's working on. I myself propose writing a lite-client module on top of the tonlabs/ever-adnl library.

3. [In case of a positive answer from 1] Are you interested in sponsoring Rust Lite Client Instead of tonlibjson footstep to support this initiative?
