feat(gnodev): txs manipulation ability

[gfanton]

This PR adds the ability to manipulate transactions:

• Users can cancel and redo a transaction from the terminal UI using the P and N commands.
• Users can save the current state from the terminal UI using Ctrl+S and restore it later with Ctrl+R (reset command).
• Users can export the current state in a genesis doc format from the terminal UI using the E command.
• Users can load and extract transactions from any genesis file using the -genesis-file flag.

TODO:

• Add documentation.
• Add unit tests.

Is there any way to just load a tx each time it starts without having to first export the entire state? Also, it doesn't seem consistent to have a separate flag for balances but not for transactions when they are both part of the genesis file. Maybe they could be all combined into the genesis file and let the user choose the file contents -- one of three options:

• it is an actual genesis data struct
• it is only balances
• it is only txs

Though that could be confusing. I think it is fair to say that someone would want to only start the node with a single tx without having to first export the entire state -- much the same how someone would want to start the node with a single balance without having to first export the entire state. So maybe they should be three separate flags where the genesis file always gets loaded first and any additional balances or txs are appended.

[gfanton]

@deelawn Good point. I will merge your PR (#2281) and then rebase this one on it. I will then update this PR so genesis-file also loads genesis balance, and let it be overridable by txs-file and/or balances-file.

[gfanton]

Thinking more about this, I believe we should not authorize balance-file and/or txs-file along with genesis-file, as it would make things more complex and is likely not very useful. If we find a use case for this in the future, we can revisit and rework this part.

[deelawn]

Nice job. I left a few nitpick comments and questions. The feature to apply and undo transactions is pretty cool 😎

Waiting on @leohhhn to update the documentation

Amazing feature, salute 🫡

Wen state viewer in gnodev

@gfanton
Just a nitpick, not all of us are fluent in Amino binary :)

[gfanton]

@zivkovicmilos I will updated this in a future PR. At the moment, it doesn't take into account the type of the event and just logs it with a %v. Improving gnodev log is definitely on my to-do list :)

[leohhhn]

Played around with it a bit, super cool. Docs look good 💯
