v3.0.0

This release adds support for date-fns v3. Thank you @christopherklint97 (#265) and everyone who helped test and fix the beta releases.

BREAKING CHANGES

• date-fns v2 is no longer supported
• Renamed utcToZonedTime to toZonedTime to make the name less confusing, just search & replace
• Renamed zonedTimeToUtc to fromZonedTime to make the name less confusing, just search & replace
• All functions are now exported using named exports, this requires changing direct
  imports from import formatInTimeZone from 'date-fns-tz/formatInTimeZone' to
  import { formatInTimeZone } from 'date-fns-tz/formatInTimeZone'
• Functions now don’t check the number of passed arguments, delegating this task to type checkers similar to date-fns v3
• Arguments are not explicitly converted to the target types; instead, they are passed as is, delegating this task to type checkers similar to date-fns v3
• IE is no longer supported since date-fns no longer supports it
• Removed flow support since date-fns also removed it
