casecmp 2.5.0

Case-insensitive string comparison, as an API. Because ¯\_(ツ)_/¯

curl -X POST -F "a=Foo Bar" -F "b=FOO BAR" https://casecmp.staging.krystal.dev/
curl -X GET "https://casecmp.staging.krystal.dev/?a=Foo+Bar&b=FOO+BAR"
curl -X GET -H "Accept: application/json" "https://casecmp.staging.krystal.dev/?a=Foo+Bar&b=FOO+BAR"
curl -X POST -H "Content-Type: application/json" -d '{"a":"Foo Bar","b":"FOO BAR"}' https://casecmp.staging.krystal.dev/
