Allow Timeout to receive timedelta

[KalleDK]

I would love for the timeout to receive timedelta's and thereby be explicit in the code what the timeout length is. I've added a pull request with the basic created, but I would expand it to also work on the different method like get etc.

A caller-side conversion can keep the units explicit without depending on a new constructor overload. Convert timedelta to total_seconds(), rather than .seconds (which drops whole days and microseconds):

from datetime import timedelta
import math
import httpx

def seconds(value: timedelta) -> float:
    result = value.total_seconds()
    if not math.isfinite(result) or result < 0:
        raise ValueError("timeout must be finite and non-negative")
    return result

timeout = httpx.Timeout(
    seconds(timedelta(seconds=30)),
    connect=seconds(timedelta(seconds=5)),
)

Pass that timeout to Client/AsyncClient or a request method. This is a conversion workaround, not a statement about whether your proposed API should be accepted. HTTPX 0.28.1 interprets these as connect/read/write/pool timeouts, not one total wall-clock deadline. Use None explicitly when you intend to disable a phase.

Checked fractional seconds, a duration over one day, negative rejection, and propagation into all four Timeout fields. Timeout configuration.

Validation: HTTPX 0.28.1, Python 3.11.9.

Yes - this is what I do now.
