use objects instead of arrays in cli config

[jaeh]

const cliArgs = {
 options: [
 ['--arg1', '--a1'],
 ['--arg2', '--a2'],
 ],
 commands: [['cmd1', 'c1'] ['cmd2', 'c2']],
}

turns into:

const cliArgs = {
 options: {
 '--arg1': { alias: '--a1' },
 '--arg2': { alias: '--a2', }
 ],
 commands: {
 cmd1: { alias: 'c1', options: ['--c1arg1'] }, 
 cmd2: { alias: 'c2' },
 },
}

commands.cmd1.options is interesting here,
every command basically could turn into a separate cli,
including: help, default, required, options, subcommands.

once this change is implemented and the parsing works,
clis of arbitrary complexity will be configurable.
