Which issue does this PR close?

A lot of BIs uses <date expr> + INTERVAL '1 week'. This PR introduces support for parsing new types for intervals: week, decades and century. (last two were added to be similar with Postgres behaviour)

Are there any user-facing changes?

New functionality without breaking changes.

It might be nice in the future to name constants like 1200_f32 with some symbolic names

like

let YEARS_PER_CENTRY: f32 = 1200_f32;

But that is just a stylistic thing -- it isn't like the number of years in a century is going to be changed at any point in our lifetimes 🤣
