Catch unknown arguments and refer to help page (#19)

* Fix building without passing build type

* Update utl and cista

* Update fmt

Using fmt::runtime as a workaround there, I wasn't able to figure out
which change caused the compiler to complain about command not being a
constexpr.

* Update boost and zlib

* Catch unknown arguments

* Update doctest
