expanded httpx compatability

[blkmajik]

Sorry, this pull request was originally made against main instead of develop.

httpx 0.18.0 deprecated the httpx.StatusCode class. This fix allows compatibility with 0.17.1 through at least 0.22.0 vs being stuck on 0.17.1.

Description

Change over from httpx.StatusCode to httpx.codes. This is a drop in replacement for how hyperglass uses httpx in this context.

Motivation and Context

I effectively maintain a custom distribution on top of CentOS/Rocky Linux. My existing httpx version was later that what was required for hyperglass. The easiest fix was to patch hyperglass so it was compatible with httpx >= 0.17.1 instead of locked into 0.17.1.

Tests

I ran pylint and flake8 against _base.py and no errors showed up in relation to my changes. Manual examination of the 0.17.1 source and 0.22.0 source of httpx indicate that StatusCode() from 0.17.1 was just a wrapper around the httpx.codes Enum.

Manual execution of the exception raising code works with a httpx.codes() instance vs a StatuCode() instance.

import httpx
status = httpx.codes(404)
print( f'{status.name.replace("_", " ")}')
