The blitz-1.0.2_p20200524 provides libblitz.so.1.0.3 therefore
the new ebuild is renamed to *-1.0.3_pre20200524 instead of revision bump
while both use the same git-commit-sha-tarball.
Blitz++ optionally depends on dev-libs/boost[static-libs]
to allow build with Boost::serialization support
(note: cmake option is realy with typo).
USE="boost" is used to handle this option.
Add USE="doc" app-doc/doxygen build dependency to build dev docs.
Add python build time dependency.
The testsuite, benchmark, examples targets now is only conditionally build
in src_compile() and tests are ran in implicit src_test() phase.
Update live ebuild.
