Fix check exclude option

[frack113]

Fix :

• duplicate -e option
• the exclude option

Now check if the excluded validator name exist

PS D:\rootme\sigma-cli> poetry run sigma check D:\rootme\sigma\rules* -x Escaped_Wildcard -x fr
Invalid validators name : ['fr'] use 'sigma list validators'
Ignoring these validators : ['escaped_wildcard']'
