CLI calls are confusing, --help sometimes misleading

[LoannPeurey]

Is your feature request related to a problem? Please describe. The current CLI calls can get confusing, especially with a lot of options (some of them being listed as optional by argparse but being required) and when options are linked to a subcommand and must be placed after the keyword (e.g. child-project metrics . results.csv --vtc vtc aclew --recordings recs.csv will not work because --recordings should be before aclew (linked to metrics subcommand) and --vtc should be after aclew (because linked to aclew subcommand)

Describe the solution you'd like More thinking needed,

• could be technically hard to release the placement constraints
• could lead to conflicts to remove placement constraints (same options for subcommands)
• could let go of the use of argparse (because forces a certain --help format)
• explore the possibility of using typer

interactive CLI could be useful : https://medium.com/geekculture/build-interactive-cli-tools-in-python-47303c50d75 examples:

• click
• pyinquirer

(maybe look at easy to maintain / flexible GUI options like Eel)
