Ensure wheel is installed before import

[radarhere]

install_wheel calls supported_wheels.py

multibuild/common_utils.sh

Lines 447 to 448 in 07f10c3

	$PIP_CMD install packaging
	local supported_wheels=$($PYTHON_EXE $MULTIBUILD_DIR/supported_wheels.py $wheelhouse/*.whl)

and supported_wheels.py imports wheel

multibuild/supported_wheels.py

Lines 11 to 15 in 07f10c3

	try:
	from wheel.install import WHEEL_INFO_RE as wheel_matcher
	except ImportError: # As of Wheel 0.32.0
	from wheel.wheelfile import WHEEL_INFO_RE
	wheel_matcher = WHEEL_INFO_RE.match

However, in Python 3.12 I get

  Traceback (most recent call last):
    File "/io/multibuild/supported_wheels.py", line 12, in <module>
      from wheel.install import WHEEL_INFO_RE as wheel_matcher
  ModuleNotFoundError: No module named 'wheel'
  
  During handling of the above exception, another exception occurred:
  
  Traceback (most recent call last):
    File "/io/multibuild/supported_wheels.py", line 14, in <module>
      from wheel.wheelfile import WHEEL_INFO_RE
  ModuleNotFoundError: No module named 'wheel'

I expect this is related to https://docs.python.org/3.12/whatsnew/3.12.html#removed

This PR adds wheel to that earliest install command.
