Create sequence allows dangling NO

[PartiallyUntyped]

I was writing a PR for #1102, and I found a bug where a dangling No slips through in create sequence options

https://github.com/sqlparser-rs/sqlparser-rs/blob/b0b62887a2bbc464642a17e590b259411bf1c11d/src/parser/mod.rs#L8604-L8611

If a No is consumed, the case where nothing exists isn't handled.

This should be

if self.parse_keywords(&[Keyword::NO, Keyword::CYCLE]) {
    sequence_options.push(SequenceOptions::Cycle(true));
} else if self.parse_keywords(&[Keyword::CYCLE]) {
    sequence_options.push(SequenceOptions::Cycle(false));
}

I will open a PR.
