cron-parser's Issues

Doesn't support slash times with initial values

e.g. 0 1/6 * * * for "every 6h starting from 01:00" doesn't work, because this parser supports */<num> but not <num>/<num>. This is supported by Kubernetes cronjobs at least, via the Go cron format (see https://pkg.go.dev/github.com/robfig/cron/v3#hdr-Special_Characters)

Thanks for all the other work here!

Program panicked when number of fields less than 5

I got error when i parse wrong cron expression: * * * *

index out of bounds: the len is 4 but the index is 4

And i found this line try to get field by index 4:

cron-parser/src/lib.rs

Line 187 in 37500d2

let do_w = parse_field(fields[4], 0, 6)?;

Then i found these line checked if number of fields greater than 5, will throw a error:

cron-parser/src/lib.rs

Lines 123 to 125 in 37500d2

	if fields.len() > 5 {
	return Err(ParseError::InvalidCron);
	}

Should we throw a error if number of fields less than 4? Like this:

if fields.len() != 5 {
    return Err(ParseError::InvalidCron);
}
