Option --noconf ignores the config file.

Feature:
To use the global config, set --global-conf (ignore local config file)
To use the local config, set --local-conf (ignore global config file)

If none of the options above are set, searches for a global config first (in exe dir)
and then looks for a project config file (in project dir and then parent dirs).

If config file does not exist, show error.

panics when using command simil test --test

If unused options are given, like --trim without the --noconf flag, the flag just remains unused and no error is shown.

-> Check for unused options (all options under the --noconf flag, if it is not given)

If unknown flags are provided, they are ignored but no error is shown

accept a flag --ignore-config to ignore the simil.toml config file and check without options.

flag -v, --verbose for additional info in output

Look for simil.toml first in exe dir (can set a global config like this).
If not found, look in cwd, go up dirs (parents) until a toml is found, otherwise show error.

If version is checked with -V, --version, check for new release and display message to user to update

The final result is the same (finds all similarities),
but the grouping for subsequent lines does not work.
(apparently only works when lines are subsequent in file 1,
see output 2: does not group when finding subsequent lines in file 2)

Simil searches for the config file in the exe dir first and then in cwd and its parent dirs (prefers global config).

-> should be the other way around: Searches in cwd and parent dirs first, then looks for a global config.

Using the flag --global-conf, the program should be able to be configured to ignore the local config and use the global one instead.

from -v to -V

Simil uses the filepath arguments to create a path from the cwd (filepath = cwd + / + filepath).
Create a flag like --abspath to ignore the cwd and be able to provide absolute paths to the files.

Move from self-written command line argument parser to clap crate

Add verbose lines counter for files
