Request: create a built-in request library

[Quail-Language]

Right now (as of issue creation time) Quail lacks the ability to connect to the internet. It should have a built-in internet request library (for example like requests in Python).

Request function signature suggestion:

function get(
    string url,
    dict queryParameters={},
    string|dict data={},
    list files=[],
    list cookies=[],
    dict headers={},
    dict|void auth=null,
    num timeout=-1
) {}

which can return an object with response info (content-type, headers, cookies, body, etc.)

Similar functions are suggested for other HTTP methods (POST, PATCH, etc.)
