DayName function request

[CoenraadS]

I would like to request that SEQ provides a new Date and Time function, that can take a timestamp and return if it's Monday..Sunday. I propose its called DayName, similar to MySQL function name.

Usecase: I would like to create a query that matches a message, but only on Saturday & Sunday.

I think it should support Timestamps and iso 8601 string as parameters.
Output is the literal string Monday, Tuesday etc.

Stretch goals:

Implement the other DayOf functions to match MySql:

DayOfMonth -> Return the day of the month (0-31)
DayOfWeek -> Return the weekday index of the argument
DayOfYear -> Return the day of the year (1-366)

Realized this is covered by DatePart: https://datalust.co/docs/working-with-dates-and-times#the-datepartdatetime-part-offset-function

I was only looking at the CheatSheet which doesn't mention it.
