Subject: [PATCH] BLD: limit support of pyparsing to <3

Due to a number of issues with the 3.0.x releases of pyparsing having issues,
we are going to for mpl3.5.0 limit to the 2.x series of pyparsing.  There is
ongoing work on both the Matplotlib and pyparsing sides and we anticipate that
we will be able to lift this constraint in the next patch release.
