support exclude argv for ttag-cli extract function

[leeabc]

Description

This PR adds a new exclude option to the extract command in ttag-cli, allowing users to exclude specific files or directories from the extraction process. The exclude option takes an array of strings, which can be either file or directory paths to exclude.

The implementation includes a new --exclude or -e flag in the yargs configuration object, which passes the value of argv.exclude to the extract function. The function then uses this array to exclude the specified files and directories from the extraction process.
