Consider removing Axios in favor native `fetch`. Personally I would recommend to use [unjs/ofetch](https://github.com/unjs/ofetch) which works in all environments (node, browser, worker). Motivation: - Bundle size: In serverless environments, and especially on edge workers, every kb counts and `deepl-node` is adding another unnecessary library by using Axios - deepl-node doesnt work on the edge: Axios is not working on non-node environments (without use of fetch adapter), this would resolve #64 - Using fetch, e.g. with `ofetch` as a wrapper, makes deepl-node work on all Node-like environments like Deno, Bun, Cloudflare Workers, etc. Possibly with this refactoring a second package could be added that is independent from node, e.g. by removing things like `fs`. This package could then be used by deepl-node as a base.
