ElrsTelemWidget v6

• Widget now selects its render size based on my artistic decision about how small each mode can be, rather than the average size of the widget space. This means that some smaller widgets (x3 size in particular) will now display more information if there's more space for the widget, such as removing trims and flight mode and sliders OR removing the top bar. Previously it was a lot more conservative about upgrading to the more dense layouts. FIXES: half screen widget size rendering as quarter screen widget size (no round range circle) when all items are turned on and the current flight mode has a user-entered name
• Range bar and circle smoothly transitions between updates
