Relative days of the week are not parsed

Problem

Relative days of the week (e.g. "last monday") are not parsed

GNU date seems to handle relative dates without issue.

Tested using coreutils v0.0.30

Example

# last monday
❯ date -d 'last monday'
Mon Mar 10 12:00:00 AM EDT 2025

❯ uutils-date -d 'last monday'
uutils-date: invalid date 'last monday'

# next monday
❯ date -d 'next monday'
Mon Mar 17 12:00:00 AM EDT 2025

❯ uutils-date -d 'next monday'
uutils-date: invalid date 'next monday'

Also extends to hours, probably any relative timestamp:

jak@jak-t14-g3 ~/P/D/apt (solver3)> ~/.cargo/bin/coreutils  touch -m -d "now + 1 hour" README.md
touch: Unable to parse date: now + 1 hour

touch: Unable to parse date: now + 1 hour

This is actually unrelated. It's just a minor issue with how this crate parses numbers:

$ date -d "now + 1 hour"
Mon Apr 21 01:33:19 PM PDT 2025

$ cargo run -q date -d "now + 1 hour"
date: invalid date 'now + 1 hour'

$ cargo run -q date -d "now +1 hour"
Mon Apr 21 13:33:29 PDT 2025

I made a separate PR for it than for the original issue: #129
