add CaseInsensitiveValues param to ParserSettings

[regme]

for parsing enum values in caseInsensetive way

[nemec]

Looks great. Only comment: Can you change the name of the setting to CaseInsensitiveEnumValues? I don't want to mislead users into thinking that -u https://google.com/ABC is the same as -u https://google.com/abc (string/Uri value) with that setting turned on.

All done! 👍
Thank you for your comment!

Can you also add one test case (with 3-4 InlineData points) for the parser where the value is True? Feel free to use this test case as a starting point.

Added some tests 👍

✔ Parse_enum_value_ignore_case(arguments: ["--colors", "0"], expected: Red)
✔ Parse_enum_value_ignore_case(arguments: ["--colors", "1"], expected: Green)
✔ Parse_enum_value_ignore_case(arguments: ["--colors", "2"], expected: Blue)
✔ Parse_enum_value_ignore_case(arguments: ["--colors", "blue"], expected: Blue)
✔ Parse_enum_value_ignore_case(arguments: ["--colors", "green"], expected: Green)
✔ Parse_enum_value_ignore_case(arguments: ["--colors", "red"], expected: Red)

This is an awesome pull request. Textbook! I would have merged this myself but since @nemec provided the initial feedback, I leave it to him. Good work. :)
