docs: document requirements for browsers

[stepin]

Something like https://caniuse.com/?search=wasm or even link(s) to it with required components.

As user of this library I need to understand limitations on browsers. I assume that library supports latest browsers but it's unclear if all current browsers in use are supported or not.

It will be really nice to have such description.

@stepin Thanks for the feedback! You're absolutely right—it’s important to clarify the browser requirements for this package. We’ll update the documentation with clear information on the required browser features:

WASM support
ECMAScript 2015 support

We aim to support all major modern browsers, but we’ll also provide more details on any limitations or unsupported browsers to ensure clarity
