Support pyparsing version 3

[lorenzncode]

• Change pyparsing usage to be compatible with version 3 ( cadquery incompatible with pyparsing 3.x #906 )

  upcaseTokens -> pyparsing_common.upcaseTokens

This PR is incomplete - could someone update the conda build dependencies to specify pyparsing version 2.1.9 and later?
I do not know how to verify/test the conda build.

I've run the cadquery pytests with pyparsing versions (passing in all cases):
3.0.3
3.0.0
2.4.7
2.4.0
2.1.9

Tests will fail with pyparsing 2.1.8 and earlier.

Merging to fix all the builds. Thanks @lorenzncode

I think the conda builds are each tested as part of the build process as there is a pytest command in the meta.yml.

Perhaps that limit on pyparsing could be removed from the meta.yml and the conda package could be built locally (which tests during the build process)

cadquery/conda/meta.yaml

Lines 27 to 35 in 5147dd8

	test:
	requires:
	- pytest
	- docutils
	- path
	source_files:
	- tests/
	commands:
	- pytest -v

I just build a conda package and it passed the tests without the pyparsing limit. Here is the commands I used

git clone git@github.com:CadQuery/cadquery.git
cd cadquery
conda create --name build python=3.9
conda activate build
conda install -c conda-forge boa
>>> edit conda/meta.yml to have a hardcoded PACKAGE_VERSION and PYTHON_VERSION and remove pyparsing version limit
