Bumped the app version to 0.2.102

- Added localTime(timeZone:) and updateTime(timeZone:) to AmtrakDateFormatting to format the current time for a given timezone.
- In ContentView, make AmtrakDateFormatting is now a shared property with localTimeZone being used at the bottom to show "It is <time> at <station> station".
- trainStatus now saves the station name and timezone (avoiding repeated formatter instantiation) and isOnTime uses the shared formatter.

 This was intended to solve a rather awkward dilemma. I turned a bunch of online Amtrak status boards made by [Dixieland Software](http://dixielandsoftware.net/Amtrak/status/StatusMaps/) into PWAs (standalone web apps) for stations that I viewed on Virtual Railfan. While it was convenient - don't get me wrong - I had to create a new web app for each and every station, and it was becoming overwhelming.
 
-So I created simple frontend that mapped to Dixieland Software's API using Tauri. You could type in simple station code and it'd take you their status board from within the app. Simple, right? Unfortunately, I didn't know how to get it go back to change the station, my attempted UI redesigns kept failing, and I accidentally botched a migration to Tauri 2.0.

I'm just not that good with Node.

+
+## 0.2.102
+
+- The status bar at the bottom now shows ``It is <time> at <station> station``.
+
+## 0.2.101
+
+Completely rewrote from scratch (except the ported models) using [SwiftCrossUI](https://github.com/moreSwift/swift-cross-ui). This new version now adopts to whatever system it was compiled for. A huge step above from pointing to a web page. While this did involve a lot of work to get it back up to speed, it was wroth it.
+
+## 0.1.104
+
+- New buttons for major terminals and rail cams.
+- Version displayed above credits.
+
+## 0.1.102
+
+- Redesigned icons
+- Added banner above form
+
+## 0.1.101
+
+- First public prototype
