2.18.0

This release adds support for pex3 cache {dir,info,purge} for
inspecting and managing the Pex cache. Notably, the pex3 cache purge
command is safe in the face of concurrent PEX runs, waiting for in
flight PEX runs to complete and blocking new runs from starting once the
purge is in progress. N.B.: when using pex3 cache purge it is best to
install Pex with the 'management' extra; e.g.:
pip install pex[management]. Alternatively, one of the new Pex scie
binary releases can be used.

In order to release a Pex binary that can support the new pex3 cache
management commands first class, a set of enhancements to project
locking and scie generation were added. When using --project you can
now specify extras; e.g.: --project ./the/project-dir[extra1,extra2].
When creating a Pex scie, you can now better control the output files
using --scie-only to ensure no PEX file is emitted and
--scie-name-style to control how the scie target platform name is
mixed into the scie output file name. Additionally, you can request one
or more shasum-compatible checksum files be emitted for each scie with
--scie-hash-alg.

On the locking front, an obscure bug locking project releases that
contain artifacts that mis-report their version number via their file
name has been fixed.

Finally, the vendored Pip has had its own vendored CA cert bundle
upgraded from that in certifi 2024.7.4 to that in certifi 2024.8.30.
