* refactored the static location screen to the location sharing screen

# Conflicts:
#	UnitTests/Sources/LocationSharingScreenViewModelTests.swift

# Conflicts:
#	ElementX.xcodeproj/project.pbxproj

* implemented a custom pin with an overlayable view

* implemented the render of the user when the location is sender instead of the pin type

* removed description and body they are not used at all.

* reimplemented single button for sharing this or user location + implemented an experimental way to update annotations

* removed unnecessary @Suite description

* implemented a way to display the alert on top of the sheet and added a spinner to the center user location button

* fixed alerts strings

* fixed a failing test

* improved preview tests
