feat(memory): Tokens that switch between MiB and GiB (#2488)

Browse Source 
* feat:add tokens to display memory in MiB when GiB val <= 1.0 (#2472)

* fix: correct swap_used calculation

* fix: pass variable by reference rather than by value

* fix: add precision arguments to filesize_gib_mib(); better condition

* doc: add #2472 to CHANGELOG

* fix: missing default argument values

* Apply suggestions from code review

### Added
- `internal/memory`: New tokens `%used%`, `%free%`, `%total%`, `%swap_total%`,
`%swap_free%`, and `%swap_used%` that automatically switch between MiB and GiB
when below or above 1GiB.

- Option to always show urgent windows in i3 module when `pin-workspace` is active
