The option() command expects a help string between the variable and the
initial value.

The intent of ": 1" is to use individual bits to store the bool state of
these class values. Because true != 0, this worked. But it was likely to
bite someone sometime. (My bad: 0fe17e22f6.)
This commit also adds m_accepts_optional_like_value to the bit field and
sets the default false value in the constructor.
Because we cannot set a default value during declaration (until C++20).
make sure future coders know to set the preferred default in the
constructor.

This replaces the verbiage copied from the Python argparse documentation
and makes the code sample more concrete. This illustrates how to avoid the
multiple help output problem reported in #165.

The previous regex would also analyze doctest.hpp. We don't need to check
a vendored library.

Added ARGPARSE_INSTALL
This allows a separate project using argparse through CMake FetchContent_Declare(...) to install the project without having to also install argparse.
Resolves the following error during stage one of clang-tidy-pr-comments:
"error: 'argparse/argparse.hpp' file not found [clang-diagnostic-error]"

Resolves the following build error:
CMake Error at CMakeLists.txt:26 (ADD_EXECUTABLE):
Target "ARGPARSE_SAMPLE_custom_assignment_characters" links to target
"argparse::argparse" but the target was not found. Perhaps a
find_package() call is missing for an IMPORTED target, or an
ALIAS target is missing?

std::less<Key> is the standard's default comparison function, we do not
need to re-declare the same function.

This action runs clang-tidy with results saved to a file which is then
parsed in stage two to post code comments. This multistage process lets
us post PR comments on code from forks.
