Change Axios to Xior to enable acme-client run on Cloudflare Worker.

[PIKACHUIM]

Hello, node-acme-client is an excellent project!
I hope to use for the development of Cloudflare Worker.
However, when I was using Client.creatOrder in the Hono based Worker project, I encountered an error:

X [ERROR] AxiosError: There is no suitable adapter to dispatch the request  - adapter http is not available in the build

After searching, it was found that 'Axios.request' is incompatible with Service Worker
It needs to be replaced with Xior to work.
I believe there is a possibility and requirement for compatibility with Service Workers in this project
So I request a change to change Axios to Xior
Content that needs to be modified:

http.js

...
import xior from 'xior';
...
    async request(url, method, opts = {}) {
        ...
        // const resp = await axios.request(opts);
        let resp = await xior.request(opts);
        const headers = {};
        for (const [key, value] of resp.headers) {
            headers[key] = value;
        }
        resp.headers = headers
        ...
    }
...

This is just a suggestion. If you could make any modifications, I would greatly appreciate it.
Actually, I have forked one and made modifications to make my Worker work properly
