ddc-hi-rs's Issues

deploy 0.4.1

and yank 0.4.0 because it fails to build on windows

There is an issue with database entries, it seems to be empty. 

I2cDevice 22785: Some("ACR") Some("VG280K")
Database {
    entries: {},
}
I2cDevice 22786: Some("ACR") Some("VG270 S")
Database {
    entries: {},
}

and the code I ran:

    use ddc_hi::{Ddc, Display};

    for mut display in Display::enumerate() {
        display.update_capabilities().unwrap();
        println!(
            "{:?} {}: {:?} {:?}",
            display.info.backend,
            display.info.id,
            display.info.manufacturer_id,
            display.info.model_name
        );
        println!("{:#?}", display.info.mccs_database);
    }

System Specs:
rust 1.68
arch linux
nvidia rtx 3050 8gb gpu
both monitors are connected via the gpu.

Error when trying to get capabilities

Hello,

I've been trying to use your crate unsuccessfully. When trying to get the capabilities of my screen, I get this error :

The unwrap returns thread 'main' panicked at 'called Result::unwrap() on an Err value: Failed to read capabilities string

And the detail is : An error occurred while transmitting data to the device on the I2C bus. (os error -1071241854)'

I'm on Windows, and I don't understand why it's having an error about I2C, while it's supposed to be using winapi to communicate with the screen (and the display.info.backend value indeed is"winapi").

Remove nom 3 dependency (replace edid)

Hi, when build my app that depends on ddc-hi I get this error message: warning: the following packages contain code that will be rejected by a future version of Rust: nom v3.2.1. The crates that seem to be relying on nom v3.2.1 are mccs (including mccs-caps and mccs-db) and edid. I tried looking into cargo's patch feature but the outdated crate seems to be in several places and I'm not sure I could update everything and have it all work, Cargo.lock is there for a reason.

Feature: Get display using identifier

Hi, is this possible to get a display using some kind of generated UUID?
I'm struggling to make my code work using this way: https://github.com/ThalusA/ddc-enhanced-rs/blob/master/src/lib.rs
The only problem is that when I get or set the brightness enhanced_display.inner_display.info.mccs_database.get or enhanced_display.inner_display.handle.get_vcp_feature seems to enter into some kind of deadlock state because it's just doing nothing and my program won't stop.
