Add TUI for command `top`

[Krysztal112233]

The current top command does not implement a TUI, it simply implements information collection and output.

Hi, I’d like to work on this.

@r3yc0n1c sure, go ahead :)

can we use something like https://ratatui.rs/ ?

[cakebaker]

Yes, I think that's fine. As I never used it before I don't know how suitable it is for this task, though.

thanks... looking into it.

hey @cakebaker, here's a POC of the TUI for top, built with the help of ratatui.rs. Currently, the top block is static string as it still needs to be implemented in the top.rs main file. Everything else is dynamically pulled from the main top.rs file. The TUI exits when we press 'q'.

Looks good :)
