Basic http

[0xor1]

adding the basic http client with byte limiting, doesn't allow for streaming requests, but should be good enough for most use cases.
this is the matching change on the dry-er arg type checking.

basic usage:

fmt := import("fmt")
http := import("http")

res := http.do("GET", "http://example.test", {"my-header": "why not"}, bytes("this is the body"))

fmt.println(res.code == 200) // true
fmt.println(res.status == "200 OK") // true
fmt.println(len(res.headers) > 0) // map, true
fmt.println(len(res.body) > 0) // bytes, true

looks like it's failing because it's using go 1.13, I developed in go 1.16 any reason the project go version isn't keeping with latest go?

Unless we’re releasing a new major version I’d prefer this be backwards compatible with older Go versions, at least to a version or two before the current version at the time of the 2.0 release of tengo.
