Add fps counter row to bottom of edi

[nazmulidris]

Just like in the tui/examples/demo/* add an FPS/telemetry display to bottom of edi.

Here are links to code in the codebase (tui/examples), where you can find the existing FPS/telemetry display:

1. https://github.com/r3bl-org/r3bl-open-core/blob/main/tui/examples/tui_apps/ex_app_no_layout/app_main.rs#L564
2. https://github.com/r3bl-org/r3bl-open-core/blob/main/tui/examples/tui_apps/ex_app_with_1col_layout/app_main.rs#L325
3. https://github.com/r3bl-org/r3bl-open-core/blob/main/tui/examples/tui_apps/ex_app_with_2col_layout/app_main.rs#L451
4. https://github.com/r3bl-org/r3bl-open-core/blob/main/tui/examples/tui_apps/ex_editor/app_main.rs#L884
5. https://github.com/r3bl-org/r3bl-open-core/blob/main/tui/examples/tui_apps/ex_pitch/app_main.rs#L412
6. https://github.com/r3bl-org/r3bl-open-core/blob/main/tui/examples/tui_apps/ex_rc/app_main.rs#L500

And the edi codebase (cmdr/) where this can be added is here:

PLMK if you have any questions 👍
