This adds a new "raw executor" (next to the "shell executor") that allows hyperfine to execute commands directly without any intermediate shell. The command line is split into tokens (using the `shell-words` crate), and according to POSIX rules. The first token is taken as the executable, and the rest as arguments. The new executor is enabled by default. In order to select the shell executor, users will have to pass `--shell=default`. This allows us to reduce measurement noise and to benchmark very quick commands. It also decreases the time to run benchmarks, as we don't need the calibration phase. Also, it allows one to make sure that the executed command is not implemented as a shell builtin. For example `hyperfine true` and `hyperfine --shell=default true` return different times due to the fact that `bash` executes `true` as a NOP. Co-authored: Ciprian Dorin Craciun <ciprian@volution.ro>
