feat: works as command runner

[sigoden]

argc will works as command runner.

You create build script named argcfile

#!/bin/bash 
set -eo pipefail

# @cmd Test all crates and modules
# @alias t,test
tst() {
    cargo test --all
}

# @cmd Format/clippy code
fmt() {
    cargo clippy --all --all-targets
    cargo fmt --all
}

eval "$(argc --argc-eval $0 "$@")"

run argc equals to bash argcfile， argc will search for argcfile then execute it. like make/makefile.
