A way to play faster and fixes for iOS 16

Version 1.37.0 includes a way to play faster, fixes for iOS 16 and some other small enhancements. The changes in detail:

• When a sum value for a row or column is tapped, empty squares are automatically converted to blocks if the number of empty squares exactly matches the number of blocks still needed. This can help to speed up play!
• When a puzzle is in play, the size of the puzzle is now shown for reference. This new feature can be turned off in the settings, if not required.
• When dark mode is in operation and “dark” has been selected as the dark-mode appearance, the sum values are shown in yellow, instead of dimmed white. This makes the sum values easier to distinguish from numbers set on squares in the puzzle grid.
• Fixes for some layout and transition issues when running on iOS 16.
• More improvements to the help explanations.

The new technique for speeding up play is described in more detail in the FAQ section on playing a puzzle - please see the question "is there an easy way to fill the gaps in a row or column when the positions of the blocks are known?".
