Remove unnecessary #define CATCH_CONFIG_MAIN to comply with the Catch2 tutorial, credits to @thodkatz for the catch (no pun intended :P)

Replace the unacceptable disgrace called parsing based on spaces with new, readString() based method. Also write some tests for insertion and calling, and general code cleanup and reformatting.

Be quiet Vera!

I said be quiet Vera! And you, clang-tidy, do not even think about raising your voice!

Fix a blunder with the test version of call()

Attempt to calm down clang-tidy and fix some stupid warnings in my CRC code (nothing much, just turned the counter int in a for-loop into a uint32_t to shut gcc up)

Comment out the empty constructor to mute clang-tidy's warning about trivial constructors

Changed tests for these functions

I was really proud of my commits today, vera loved them. But the dreaded moment has arrived comrades.
