This package allows Python scripts to handle compressed blend files (see
rB2ea66af742bc). This is for example needed by Blender Asset Tracer to
send files to a Flamenco render farm.
This change includes a new `WITH_PYTHON_INSTALL_ZSTANDARD` build-time
option, to control whether to actually install the package. For this the
already-existing approach for Requests was copied.

Nowadays `requests` no longer depends on `chardet` but on
`charset-normalizer`. That project describes itself as:
> A library that helps you read text from an unknown charset encoding.
> Motivated by chardet, I'm trying to resolve the issue by taking a new
> approach. All IANA character set names for which the Python core library

Building NumPy from source with default options of builder
causes it to link against Accelerate framework which is buggy and
raises a warning mentioned in [2].
"RankWarning: Polyfit may be poorly conditioned"
Accelerate is deprecated with NumPy 1.20+.[1]
So either we build OpenBLAS in dependencies also and set appropriate
env variables suggested in [1] while building NumPy for it to find
OpenBLAS. Or download NumPy wheel from pip and never allow pip to
build NumPy from source while installing.
After this change, pip wheels are used for NumPy for macOS with x86_64.

For the debug version of cython pip was trying to link
against the release version of python for some strange
reason. Passing some flags to explicitly target the
debug version fixes the issue.
Given other platforms do not have different builds for
debug/release this is not an issue there.
The following packages also have received updates:
- IDNA 2.10
- CHARDET 4.0.0
- URLLIB3 1.26.3
- CERTIFI 2020.12.5
- REQUESTS 2.25.1
- NUMPY 1.19.5
numpy has gained a hard dependency on cython:
- CYTHON 0.29.21
Notes:
- This only updates the build environment files,
once these are built, Blender can default to Python 3.9.
- The 'm' suffix for Python binaries/libs has been removed.
- The macOS patch in Python 3.7 is has been removed.
