Add better support for command arguments

[dolphinau]

Fix #48 #50

Currently, we have a low command argument support that miss some potential code execution done in parenthese expression or braced expression
This PR aims to improve support by handling

• Variables and braced variables in command arguments
• Parenthesis experession
• Braced expression

I didn't add the auto generated files one purpose yet because the PR is not ready

WIP:

• Added scanner to add concat support for variables in args
• Added support for command arg names/value with potential ":" separtor
  • Does is work also with a " " separator?
  • Fix support for -argname:value and assert that value can be expendable
• Add parenthesis/braced experession
  • Fix issue with toto(toto)toto that doesn't properly parse the last toto because there is no " " separtor between parenthesis expression and standard expression
• Fix tests
