Support the UTM coordinates format

[thirzaverhoeven17]

Original user message (titled "Switch to UTM coordinates"):

Hey,

I really like your app! I use it a lot
Maybe you could make an option to put the coordinates in UTM instead of longitude and latitude. In that way it is easier to use together with paper maps and gps

Feature description

The app currently supports the following coordinates format in latitude + longitude:

• Decimal degrees
• Degree + decimal minute
• Degree + minute + second

This enhancement would add support for the UTM coordinates format.

Required change 1: update the app settings

The app settings currently allow the user to select between different coordinates formats to use throughout the app, the new UTM coordinates format option should be added there.

Required change 2: update the coordinates floating widget

Update the floating widget displaying the coordinates currently located at the center of the screen to support displaying UTM coordinates.

Required change 3: update the coordinates edit window

The coordinates edit window allowing the user to edit, copy and paste coordinates should be updated with the following new behaviors:

• Edit text field: support highlighting the coordinates text field in green or red depending on whether the coordinates are valid
• Copy button: support copying the currently edited UTM coordinates to the clipboard
• Paste button: support overwriting currently edited UTM coordinates with new coordinates from the clipboard if the clipboard contains valid coordinates

Thanks for creating this feature request, I've redacted it to outline the things that need to be done.
