embedded-graphics 0.8.0+ compatibility

[orsinium]

When trying to use pybadge-high with embedded-graphics 0.8.1, I get multiple errors about missed methods and unsatisfied traits on the display

#![no_std]
#![no_main]

use embedded_graphics::{
    mono_font::{ascii::FONT_6X10, MonoTextStyle},
    pixelcolor::Rgb565,
    prelude::*,
    text::Text,
};
use pybadge::{prelude::*, *};
use pybadge_high as pybadge;

#[entry]
fn main() -> ! {
    let red = Color::new(255, 0, 0);
    let mut pybadge = PyBadge::take().unwrap();
    // pybadge.display.clear(red).unwrap();
    let style = MonoTextStyle::new(&FONT_6X10, Rgb565::WHITE);
    Text::new("Hello Rust!", Point::new(20, 30), style)
        .draw(&mut pybadge.display)
        .unwrap();
}

I have check this. Pybade-high is only a small wrapper over the edgebadge crate, which a more easy api. However the edgebadge crate still stuck at st7735-lcd-rs 8.0.1, which does not support embedded-graphics 0.8 yet. So we need to wait for an update of the edgebadge crate( or fork it).

Looks like the edgebadge crate is a bit outdated and unmaintained. Anyway I have open an issue for this now to discuss this issue: https://github.com/atsamd-rs/atsamd/issues/724
