c2920ea334 fw-rust: Break everything down in multiple files
All checks were successful
ci/woodpecker/push/woodpecker Pipeline was successful
Details 
To reduce length of `main.rs` and therefor improve readability create
source files for:

- Assets (`assets.rs`): Contains all graphical assets such as the
  splash screen assets, symbols and the symbol table.
- LCD (`lcd.rs`): Contains all lower level things regarding the LCD
  such as the `Lcd` struct and its implementations.
- Screen (`screen/mod.rs`):
    - Splash (`screen/splash.rs`)
    - Home (`screen/home.rs`)
    - Setup (`screen/setup.rs`)

In the future it would probably make sense to move the LCD module into
the screen module.

91e120b258 fw-rust: Add setup screen and handle button input
All checks were successful
ci/woodpecker/push/woodpecker Pipeline was successful
Details 
To create a setup screen more symbols are created and added to the
symbol table. Helper functions are added to draw homogenous areas onto

enum. Adapt functions already handling input to those new kinds of
input. Add the setup screen construct. Add global atomics to handle
the button and the timer for handling the back input when the button
is pressed until the timer one overflows. Button press and the timer
are handled via interrupts.

use a `RefCell` contained in a `Mutex`.

Also update the build dependencies.
