Add support for wildcards in CLI test and tag filters

[cschreib]

This PR does the following:

• Adds support for wildcards (* match-all character) in filters on the command line interface, for both tags and test case names.
• Adds support for exclusions patterns (~...).
• Adds support for multiple filters on the command line, mimicking the Catch2 behavior.
• Changed the full test name for typed tests from NAME [TYPE] to NAME <TYPE> to prevent ambiguity with tags.
• Use std::chrono::steady_clock instead of high_resolution_clock, since the latter can end up being a typedef to system_clock, which is less desirable.

Note on benchmarks: For some reason I have not yet been able to identify, the runtime benchmarks on my machine have generally become slower in the past weeks. I had to re-run all the benchmarks for the competitor libraries, to compare on the same grounds. It seems that most of the run time in snitch is spent in std::chrono::steady_clock::now(), which is used to report test duration. Setting SNITCH_WITH_TIMINGS = 0 brings the snitch run time performance on par with Boost.UT. I don't know what could have changed in my machine to make time measurements much slower, but I did upgrade linux kernel and BIOS.
