 Example 2: use meson install_tags for selective installs

-It is now (meson-python 0.13 or 0.14?) possible to use meson install_tags to select which targets should be installed into the binary wheels (https://mesonbuild.com/Installing.html#installation-tags). Each meson target has a default install_tag (e.g. 'runtime' for shared libraries and 'devel' for headers.) The default tag can be overwritten for each target using the targets "install_tag" option (for more information refer mesons documentation in installation-tags).

+   Each meson target has a default install_tag (e.g. 'runtime' for shared libraries and 'devel' for headers.). Using "meson install --tags=tag1,tag2,..." will cause meson to only install the targets tagges with any of the specified tags. The default tag of each target can be overwritten using the target's "install_tag" option. Ffor more information refer mesons documentation in installation-tags: https://mesonbuild.com/Installing.html#installation-tags
 
 The following code (in pyproject.toml) causes meson-python to only install targets tagged with 'runtime' or 'python-runtime') into the binary wheel (ignoring e.g. c++ headers):
