This commit improves the way months are recognized in pivot functions.
It also removes the use of `moment.js` which will be removed in the future
(see task 3391739)
Currently, months in a pivot function must follow a very specific
format.
It must be mm/yyyy
`ODOO.PIVOT(1, "amount", "date:month", "01/2020")`
Among other things: "1/2020" does not work, it must be prefixed by a
leading zeros.
Now, any date-like value would work:
month: "1/2020"
first of the month: "1/1/2020"
any day in the month: "1/2/2020"
using the DATE function: DATE(2020, 12, 1)
using NOW()
Future work: `PIVOT.HEADER` should return a the date as a number
when the date is a month. But it's currenctly quite a mess.
because we use the same method for a million things (`getGroupByDisplayLabel`).
