New/Fix: Remove dayjs dependency

We have been working toward making Chrono relying only on native Javascript date/time library; and now we are ready to drop dayjs dependency.

This change removes ParsingComponent.dayjs() and dayjs from package.json (50585af). Thus, it is published in a minor version.

New/Fix: Reference date calculation on the assigned timezone 4033a27

Previously, the reference date calculation (e.g., "1 day ago", "tomorrow at 9am") was based on the interpretation of the reference instant/timestamp using the system timezone rather than the assigned timezone (e.g., "April 5" in the system timezone may already "April 6" in the assigned timezone).

const refInstant = new Date("2025-02-27T22:00:00.000Z");
// This instant/timestamp
// = Thu Feb 27 2025 15:00:00 GMT-0800 (PST)
// = Fri Feb 28 2025 08:00:00 GMT+0900 (JST)
chrono.parseDate("Tomorrow at 9am", { instant: refInstant, timezone: "PST" })
// In PST, "Tomorrow at 9am" => Fri Feb 28 2025 09:00:00 GMT-0800 (PST)
chrono.parseDate("Tomorrow at 9am", { instant: refInstant, timezone: "JST" })
// In JST, "Tomorrow at 9am" => Sat Mar 1 2025 09:00:00 GMT+0900 (JST)

This changed some current relative date/time output. So, it is published in a minor version, instead of a patch.
